What does the weight of an object depend on?
A. Time taken for an event to occur
B. Temperature of the object
C. Force of gravity
D. Atmospheric pressure
Answer:
The Answer is C. The force of gravity
Explanation:
This is because it is the force of gravity exerted or inflicted upon the object or organism. With more gravity inflicting upon an object the heavier it feels. In fact, weight and gravity have such a close relationship that the equation for weight is F = M x A where F represents the objects weight in Newtons, M equals it's mass, and A represents the downward acceleration due to the gravity.

A dolphin can swim at a constant speed of 12.5 m/s. How
long does it take a dolphin to swim 45 meters?
Answer:
[tex]\boxed {\tt 3.6 \ seconds}[/tex]
Explanation:
Time can be found by dividing the distance by the speed.
[tex]t=\frac{d}{s}[/tex]
The distance is 45 meters and the speed is 12.5 meters per second.
[tex]d= 45 \ m \\s= 12.5 \ m/s[/tex]
[tex]t=\frac{45 \ m}{12.5 \ m/s}[/tex]
Divide. Note that the meters, or "m" will cancel each other out.
[tex]t=\frac{45 }{12.5 \ s}[/tex]
[tex]t=3.6 \ s[/tex]
It will take the dolphin 3.6 seconds to swim a distance of 45 meters are 12.5 meters per second.

Which chemical bond has a low melting point? Why does this bond have low melting points? A common compound that this bond produces is used in our everyday life. SUGAR!
Answer:
1,2: When simple molecular substances melt or boil, it is these weak intermolecular forces that are overcome. The covalent bonds are not broken. Relative little energy is needed to overcome the intermolecular forces, so simple molecular substances have a low melting and boiling points.
3: Water, Almost no living thing can survive without water. Water is everywhere on our planet. It is the reason we have an organic life on earth. A water molecule consists of one oxygen atom combined with two hydrogen atoms. We use water throughout day and night; in drinking, cooking, household needs, industries, and agriculture. Apart from these general uses of water, you might be amazed to know that water plays a major role in volcanic eruptions.

A mortar shell is accidentally shot straight up with an initial speed of 147 m/s. How long does it take for the shell to reach its maximum height? How high does the shell rise? If the shell falls straight down after is stops, what is its velocity when it hits the ground? What is the total time the shell is in the air?
Answer:
1) t ≈ 14.985 seconds
2) The maximum height reached ≈ 1101.4 meters
3) The velocity with which it hits the ground = 147 m/s
4) The total time in the air ≈ 29.969 seconds
Explanation:
1) The given information are;
The initial velocity of the mortar shell = 147 m/s
The direction of the mortar shell = Vertically upwards
Therefore, we have, from the equation of motion
v = u - g·t
Where;
v = The final velocity = 0 at maximum height
u = The initial velocity = 147 m/s
g = The acceleration due to gravity = 9.81 m/s²
Therefore, we have;
0 = 147 - 9.81 × t
9.81 × t = 147
t = 147/9.81 ≈ 14.985 seconds
t ≈ 14.985 seconds
2) From the equation of motion, v² = u² - 2×g×s
Where;
s = The maximum height reached
We have;
0² = 147² - 2×9.81×s
2×9.81×s = 147²
s = 147²/(2×9.81) ≈ 1101.4 meters
The maximum height reached ≈ 1101.4 meters
3) The velocity with which it hits the ground is equal to the initial velocity = 147 m/s
4) The total time in the air = 2 × The time it takes to reach maximum height
The total time in the air = 2 × 14.985 ≈ 29.969 seconds
The total time in the air ≈ 29.969 seconds

Your science teacher presents you with a circuit model that contains five light bulbs, a switch, and a 1.5-volt battery. The wires of the circuit are hidden from your view so that you cannot see how the bulbs are connected to the battery. How could you determine the type of circuit used in this model?
A.
If all the bulbs are equal brightness, it is a series circuit because each bulb in a series circuit has the same resistance.
B.
If all the bulbs are equal brightness, it is a parallel circuit because each bulb in a parallel circuit has its own path to the battery.
C.
If you unscrew one bulb and all the others stay lit, it is a parallel circuit because each bulb in a parallel circuit has its own path to the battery.
D.
If you unscrew one bulb and all the others stay lit, it is a series circuit because each bulb in a series circuit have to share the same current.
Answer:
C
Explanation:
PLACING BULBS IN SERIES
Increasing the number of bulbs decreases the brightness of the bulbs.
The resistance increases. In a series circuit, adding bulbs increases the resistance in the circuit. A complete circuit requires the electrons to move from the negative terminal of the battery to the positive terminal. When one bulb is unscrewed it opens the circuit preventing a complete circuit and the electrons cannot return to the battery.
PLACING BULBS IN PARALLEL
Two bulbs in parallel are brighter than two bulbs in series. In a parallel circuit each bulb is in its own circuit. As bulbs are added the resistance in the circuit decreases since each circuit is another pathway for electrons to move from one end of the circuit to the other.
If you unscrew one bulb and all the others stay lit, it is a parallel circuit because each bulb in a parallel circuit has its own path to the battery.
What is bulbs in series combination?The brightness of the bulbs reduces as the number of bulbs increases in series. Resistance rises in intensity. Adding bulbs to a series circuit raises the circuit resistance. The electrons must pass from the battery's negative to positive terminals in order for the circuit to be complete. When one bulb is removed, the circuit is broken, making it impossible for the electrons to return to the battery.
What is bulbs in parallel combination?In comparison to two bulbs in series, two bulbs in parallel are brighter. Each bulb is in its own circuit when the circuits are parallel. As more bulbs are added, the resistance in the circuit reduces because each additional circuit provides an additional route for electrons to travel from one end to the other.
You can determine the type of circuit used in this model by unscrewing one bulb and all the others stay lit, it is a parallel circuit because each bulb in a parallel circuit has its own path to the battery. Hence, option(C) is correct.

Alice and Marge are studying the properties of matter. The girls placed some an iron nail in a beaker containing water. Iron is a solid metal at room temperature. Iron is a shiny and malleable; it can be formed into shapes like the nails the girls used. Iron will turn reddish-brown in the presence of air or water as it rusts. Iron is a good conductor of electricity and heat. After 48 hours, the girls checked the nail in the water and compared it to the nail they left on the lab bench. Here is a photo of their results.
Based on the girls' experiment, what is a chemical property of iron?
Answer:
When substances made of iron are exposed to oxygen and moisture (water), rusting takes place. Rusting removes a layer of material from the surface and makes the substance weak. Rusting is a chemical change.
Answer:
B) Iron rusts in water
Explanation:
Physical property is defined as the property of a substance which becomes evident during physical changes. Example: Melting point , electrical conductivity, malleability,
Chemical property is defined as the property of a substance which becomes evident during chemical changes. Example: Reactivity with other substances
Rust is hydrated ferric oxide .
Corrosion of iron is called as rusting. Rust is hydrated ferric oxide .
Thus rusting of iron is a chemical property.

put in 33.3 for m/s and you will get 119.88 km/h.
119.88 km/h.
Answer:
33.3 s
162 km/h
Explanation:
Given:
Δx = 1500.0 m
v₀ = 45.0 m/s
a = 0 m/s²
Find: t
Δx = v₀ t + ½ at²
1500.0 m = (45.0 m/s) t + ½ (0 m/s²) t²
t = 33.3 s
Convert m/s to km/h:
45.0 m/s × (1 km / 1000 m) × (3600 s / 1 hr) = 162 km/h

A population of lobsters was recently exposed to a new disease. Which type of limiting factor is this disease and what will be its predicted impact on the carrying capacity of this population? Group of answer choices density independent; the carrying capacity will increase density dependent; the carrying capacity will decrease density dependent; the carrying capacity will increase density independent; the carrying capacity will be reduced
Answer:
the carrying capacity will decrease density dependent
Explanation:
The limiting factor of the disease is density dependent and will decrease the carrying capacity of the population because the disease that affect the population operate when the number of organisms in per unit area get to a specific level , it's affected the population when the population per unit are reached a certain level and the disease decrease the carrying capacity of the population. Carrying capacity is the average population size of organisms in an habitat. As the lobsters population is affected by disease, the population sizes reduced because many of the lobsters would of died and inactive, thereby causing a reduction in the size and capacity.

How are mass and acceleration related (if you change one of them, what happens to the other one)?
1) A football player kicks a ball at an angle of 30 and gives it a velocity of 15m/s.
A) What was the time of flight?
B) How far horizontally does the ball land?
C) How high does the ball reach?
Answer:
A) 1.53s
B) 19.8m
C) 2.869m
Explanation:
A) The time of flight for a projectile can be calculated using the formula:
t = 2μsinθ/g
Where; u = velocity
θ = angle
g = acceleration due to gravity (9.8m/s^2)
t = 2 × 15 × sin 30°/9.8
t = 30sin30°/9.8
t = 30 × 0.5/9.8
t = 15/9.8
t = 1.53s
B) The horizontal range (distance) for a projectile can be calculated using the formula:
Range = u²sin2θ/ g
Range = 15² sin 2 × 30 / 9.8
Range = 225 sin 60/9.8
Range = 225 × 0.8660/9.8
Range = 194.855/9.8
Range = 19.8m
C) The maximum height for a projectile can be calculated using the formula:
h = u²sin²θ/2g
h = 15² (sin 30)² / 2 × 9.8
h = 225 × 0.25 / 19.6
h = 56.25/19.6
h = 2.869m

.
Answer in units of m/
Answer:
5.45 m/s
Explanation:
Given:
Δx = 2.08 m
v₀ₓ = v₀ cos 44°
aₓ = 0 m/s²
Δx = v₀ₓ t + ½ aₓ t²
2.08 m = (v₀ cos 44°) t + ½ (0 m/s²) t²
2.89 = v₀ t
Given:
Δy = 0.63 m
v₀ᵧ = v₀ sin 44°
aᵧ = -9.81 m/s²
Δy = v₀ᵧ t + ½ aᵧ t²
0.63 m = (v₀ sin 44°) t + ½ (-9.81 m/s²) t²
0.63 = 0.695 v₀ t − 4.905 t²
0.63 = 0.695 (2.89) − 4.905 t²
t = 0.530
v₀ = 5.45 m/s
