Explanation: Just took the test

Answer:

a. distance = s x t

Explanation:

The equation we know for speed is speed = distance/time, shortened to s = d/t

If you want to find the distance, you'd rearrange the formula to make d the subject. To isolate d, multiply by t on both sides (since it's being divided on the right. This leads to

s x t = d, with d isolated on the right side.

Therefore, to find the distance an object travelled you'd use a. distance = s x t

Answer:

the impulse and change in momentum of the football is 18.83 N/s.

Explanation:

Given;

applied force, F = 420 N

time of force action, t = 22.3 s

The impulse and change in momentum of the football is calculated as;

J = ΔP = [tex]\frac{F}{t}[/tex]

where;

J is the impulse

ΔP is the change in momentum

J = ΔP = [tex]\frac{F}{t}= \frac{420}{22.3} = 18.83 \ N/s[/tex]

Therefore, the impulse and change in momentum of the football is 18.83 N/s.

Explanation:

λ = 3.125 m

λ = 2.83 m

Given

Frequency of radio : 96 MHz and 106 MHz

Required

The wavelength

Solution

Wavelength : from the crest to the crest of the next wave or the trough to the trough

Frequency (f): number of waves in one second

v = λ x f

λ = v : f

Input the value :

f = 96 MHz = 96 x 10⁶ Hz

λ = v : f

λ = 3 x 10⁸ :  96 x 10⁶

λ = 3.125 m

f = 106 MHz = 106 x 10⁶ Hz

λ = v : f

λ = 3 x 10⁸ :  106 x 10⁶

λ = 2.83 m

The velocity at the bottom : v = 8.85 m/s

Given

height of the hill = 4 m

Required

The velocity at the bottom

Solution

The law of conservation energy :

ME₁=ME₂

(PE+KE)₁ = (PE+KE)₂

initially at rest⇒vo=0⇒KE₁=0

At the bottom⇒h=0⇒PE₂=0

So the equation becomes :

PE₁=KE₂

mgh=1/2.mv²

gh = 1/2v²

[tex]\tt v=\sqrt{2gh}[/tex]

v = √2x9.8x4

v = 8.85 m/s

Answer:

C. The net force acting on the object

Explanation:

The second law states that the acceleration of an object is dependent upon two variables - the net force acting upon the object and the mass of the object. The acceleration of an object depends directly upon the net force acting upon the object, and inversely upon the mass of the object.

Answer:

See the answers below.

Explanation:

The cost of energy can be calculated by multiplying each given value, a dimensional analysis must be taken into account in order to calculate the total value of the cost in Rs.

[tex]Cost=0.350[kW]*12[\frac{hr}{1day}]*30[days]*4.5[\frac{Rs}{kW*hr} ]=567[Rs][/tex]

The fuse can be calculated by knowing the amperage.

[tex]P=V*I[/tex]

where:

P = power = 350 [W]

V = voltage = 240 [V]

I = amperage [amp]

Now clearing I from the equation above:

[tex]I=P/V\\I=350/240\\I=1.458[amp][/tex]

The fuse should be larger than the current of the circuit, i.e. about 2 [amp]

Answer:   Eat only when you're truly hungry instead of when you are tired, anxious, or feeling an emotion besides hunger.

Plan meals ahead of time to ensure that you eat a healthy well-balanced meal.

Keep more fruits, low-fat dairy products (low-fat milk and low-fat yogurt), vegetables, and whole-grain foods at home and at work.

Explanation:

Answer:

I know that some foods have a lot of sugar. I read online that I don’t need any more than 25 grams of added sugar a day. One kind of pop that I like to drink has 40 grams of sugar per can. I can start by drinking less pop. Next, I learned that some food makers are now putting nutrition keys on the front of their boxes. I love all kinds of breakfast cereal, so I can use the nutrition key to compare brands. Cereal high in fiber is good, but cereal high in sugar isn’t. I’ll be more careful, too, when ordering fast food. Sometimes fast-food places want to change the size of my order from medium to large for a higher price. From now on, I won’t pick the bigger meal. Picking the medium-sized meal should be better for me and can even save me money.

Answer: Work and Power

Explanation:

The formula "Fxd = W" is the formula for work. It is the cross product of how much force given some distance.

The next part, Im not sure why they used a W. It is very confusing the way they wrote it. That 'W' would be the power. Power has units of joules per second.

Answer:

For liquid at room temperature and pressure, the value of specific heat capacity (Cp) is approximately 4.2 J/g°C.

Explanation: This implies that it takes 4.2 joules of energy to raise 1 gram of water by 1 degree Celsius. This value for Cp is actually quite large. This (1 cal/g.

but what is the question here?

Answer:

2500 Newtons

Explanation:

If force equals the mass × acceleration then all should be quite simple

25kg is the mass of your car

100 m/s/s is the acceleration of you car

25kg • 100m/s/s = 2500 Newtons

Answer:

[tex]\boxed {\boxed {\sf 2500 \ Newtons }}[/tex]

Explanation:

The formula for force is the product of mass and acceleration.

[tex]F=m*a[/tex]

The mass of the car is 25 kilograms and the acceleration is 100 meters per square second. So,

[tex]m= 25 \ kg \\a= 100 \ m/s^2[/tex]

Substitute the values into the formula.

[tex]F= 25 \ kg * 100 \ m/s^2[/tex]

Multiply.

[tex]F= 2500 \ kg*m/s^2[/tex]

[tex]F= 2500 \ N[/tex]

The force of the car is 2500 Newtons.

A mousetrap makes use of a simple machine called a lever.

Explanation:

In a second-class lever the effort force is at the other end, with the load in the middle. In a third-class lever, the load is at the end and the effort force is between the fulcrum and the load. When you set the mousetrap, you are using a second-class lever. Sorry if I get this wrong. I am in 5th grade! ♥

Answer:

g = 1.25m/s²

Explanation:

Given the following data;

Mass = 5kg

Height = 6m

Gravitational potential energy = 24J

To find the acceleration due to gravity;

Potential energy can be defined as an energy possessed by an object or body due to its position.

Mathematically, potential energy is given by the formula;

[tex] P.E = mgh[/tex]

Where,

P.E represents potential energy measured in Joules.

m represents the mass of an object.

g represents acceleration due to gravity measured in meters per seconds square.

h represents the height measured in meters.

GPE = mgh

Substituting into the equation, we have;

24 = 5*6*g

24 = 30g

g = 30/24

g = 1.25m/s²

Therefore, the acceleration due to gravity on Planet X is 1.25m/s².

Answer:

g=0.8m/s^2

Explanation:

M=5kg

h=6m

GPE=24J

GPE=Mgh

g=GPE/Mh

g=24J/(5kg)(6m)=0.8

g=0.8m/s^2
