How much work is done when a porcelain vase with mass of 2.5 kg is lifted up 3 m to a shelf? (HINT- Weight can be used as Force when the motion is up/down).
For an object falling at the terminal velocity, list all the forces (magnitude and direction) acting it?
Answer:
Three stages of falling
There are three stages as an object falls through a fluid:
at the start, the object accelerates downwards due to the force of gravity
as the object's speed increases, frictional forces such as air resistance or drag increase
at terminal velocity, the weight of the object due to gravity is balanced by the frictional forces, and the resultant force is zero

The heating effect, 'E', is given by the formula, E = I²·R·t
Where;
I = The current flowing
R = The resistance of the material
t = The time the material takes to heat up
(c) The values showed by Pinki here is the value of care, concern and prevention, to prevent the harmful effect of the high heat on the skin of her daughter
Explanation:
A rubber ball moving at a speed of 5 m/s hit a flat wall and returned to the thrower at 5 m/s. Which statement
correctly describes the momentum of the rubber ball?
a. Its magnitude increased and its direction changed.
b. Its magnitude increased but its direction remained the same.
c. Its magnitude remained the same but its direction changed.
d. Its magnitude and its direction both remained the same.
Answer:
d. Its magnitude and its direction both remained the same.
Explanation:
Momentum can be defined as the multiplication (product) of the mass possessed by an object and its velocity. Momentum is considered to be a vector quantity because it has both magnitude and direction.
Mathematically, momentum is given by the formula;
[tex] Momentum = mass * velocity [/tex]
The law of conservation of momentum states that the total linear momentum of any closed system would always remain constant with respect to time.
This ultimately implies that, the law of conservation of momentum states that if objects exert forces only on each other, their total momentum is conserved.
In this scenario, a rubber ball moving at a speed of 5 m/s hit a flat wall and returned to the thrower at 5 m/s. Thus, the statement which correctly describes the momentum of the rubber ball is that its magnitude and its direction both remained the same because its velocity didn't change while returning to the thrower.
The correct statement should be "Its magnitude remained the same but its direction changed". Option C is correct.
Given information:
A rubber ball moving at a speed of 5 m/s hit a flat wall and returned to the thrower at 5 m/s.
Now, the mass of the ball doesn't change and the magnitude of the velocity is also the same.
Momentum can be defined as the product of mass and velocity. It is a vector quantity because velocity is also a vector quantity, and it has magnitude and direction.
Now, the magnitude of momentum will be the same because mass and velocity don't change in magnitude.
The direction of velocity will be reversed. So, the direction of momentum will also be reversed.
Therefore, the correct statement should be "Its magnitude remained the same but its direction changed". Option C is correct.

What is the equation used to find the image distance? Identify each variable
Answer:i f I understand your question correctly, the formula is as follows:
Note: The sign convention is based on distances which are measured from the lens to the object or image of regard. Distances measured in the same direction the light is moving are positive and distances measured in the opposite direction the light is moving are negative.
The measurements are in meters
The “ambient” index of refraction is assumed to be n=1.00
The inverse of the object distance plus the dioptric power of the lens (convex—positive and concave—negative) equals the inverse of the image distance.
Or 1/Od +Dl =1/Id
Please note, it has been a long time since I thought about teaching this concept to students.

Explain the melting of a solid in terms of molecules and energy
Heat generates energy when you melt a solid; as you heat up molecules, they move faster and begin to break apart into a liquid form.
What is the melting point?The melting point is the point at which a substance transforms from a solid to a liquid.
The melting point of a liquid is the temperature at which it transforms from a solid to a liquid at atmospheric pressure. This is the point where the liquid and solid phases are in balance.
Heat generates energy when you melt a solid; as you heat up molecules, they move faster and begin to break apart into a liquid form.
The kinetic energy of the molecule is due to the movement of the molecule as the temperature of the system increases the melting point comes closer.
As the temperature increases the kinetic energy of the molecule increases.
Hence the energy, melting point, and temperature relatively affect each other.

Train A leaves the station heading north at 80 mph. At the same time and from the same station, Train B heads south 65 mph. How far apart are the trains after 3 hours fo travel?
Answer:
The trains will be 435 miles apart
Explanation:
Distance covered by the two trains can be obtained by multiplying their speeds with the time frame under consideration - in this our case, it is 3hours.
For Train A
Distance covered = 80mph X 3 hours = 240miles
For train B
Distance covered = 65mph X 3 hours = 195 miles.
The total distance between the two trains after 3 hours will be
240 + 195 = 435 miles

Find the gravitational force between Venus (4.87 x 1024 kg) and
the sun (1.989 x 100 kg). Venus orbits at a distance of
1.082 x 10" m.
The gravitational force between Venus and the Sun, seperated at the distance of 1.082×10¹¹ m is 5.520×10²² N.
What is gravitational force?Gravitational force is the attractive force between two bodies. It is applicable to all the bodies have masses and it is called as Universal law of gravitation.
Grarvitational force is the attractive force is directly proportional to the product of two masses and is inversely proportional to the square of distance between them.
F ∝ m₁ × m₂ / d², m₁ and m₂ is the mass of two bodies and d² is the distance between two bodies. The SI unit of mass is kg and SI unit of distance is m. The SI unit of force is newton.
From the gravitational force,
F = G (m₁×m₂ / d²)
G represents gravitational constant and is equal to 6.67× 10⁻¹¹ N.m²/kg².
From the given,
m₁ ( mass of venus ) = 4.87 x 10²⁴kg
m₂ ( mass of sun) = 1.989 x 10³⁰ kg
d² ( distance between sun and venus) = 1.082 x 10¹¹ m.
G = 6.67 ×10⁻¹¹ N.m² / kg²
F = G (m₁×m₂ / d²)
= 6.67 ×10⁻¹¹ × 4.87 x 10²⁴× 1.989 x 10³⁰ / (1.082 x 10¹¹)²
= 5.520 × 10²² N
The gravitational force between the venus and sun at the distance of 1.082 x 10¹¹ is 5.520× 10²² N.

A van of mass 2500kg travelling at a velocity of 12 m/s collides with a stationary car of mass 700kg. The vehicles move together after the impact. Calculate their velocity.
Answer: 9.375m/s
Explanation: This is an inelastic collision, so the formula is mv1+mv2=(m1+m2)v-final. My work is a follows:
2500kg(12m/s) + 700kg(0m/s)=(2500kg+700kg)(v-final)
30,000kg(m/s)+0=3200kg(v-final)
30,000kg(m/s)/3200kg=9.375m/s
