A tennis ball has 10 J of energy when it is 1 m above the floor.
Name the store associated with this
energy.
Answers
The store associated with the energy when a ball has 10 J of energy when it is 1 m above the floor is gravitational potential energy
What is gravitational potential energy?
Gravitational potential energy is the energy of a body by virtue of its position in the gravitational field.
From the question, If a tennis ball has 10 J of energy when it is 1 m above the floor, first, a work of 10 J was done against gravity to lift the tennis from the floor to a height of 1 m. At the height of 1 m, the work of 10 J is converted to the gravitational potential energy of the tennis ball which is stored in the ball.
Hence, The energy associated when a tennis ball has 10 J of energy and it is 1 m above the floor is gravitational potential energy.

How is thermal equilibrium reached? Question 3 options: When both objects have the same temperature When objects have the same mass When objects are both in the same state of matter (solid, liquid, or gas) When objects have different temperatures.
Answers
In the thermal equilibrium, the change in temperature is said to be zero in between the bodies. Thermal equilibrium is reached when both objects have the same temperature.
What is thermal equilibrium?Thermal equilibrium is easily explained by the zeroth law of thermodynamics. If any two-body is at thermal equilibrium there is no change in the temperature of the body.
According to zeroth law if body A is in thermal equilibrium with body B and body B is in thermal equilibrium with C . So body A and C are also in thermal equilibrium.
In the thermal equilibrium, the net heat transfer is said to be zero in between the bodies.
Hence option A IS RIGHT. Thermal equilibrium is reached when both objects have the same temperature

Suppose that 100 g of metal gained 110 cal of heat when the temperature is increased form 60°C to 70°C. What is the specific heat of metal?
Answers
q=mcΔt
110=100.c.(70-60)
c=0.11
Answer:
110 cal kg⁻¹°C⁻¹
Explanation:
Formula to find the specific heat capacity is :
Q = m c Θ
Here,
Q = heat energy
m = mass
c = specific heat capacity
Θ = change in temperature
Now let us find the specific heat capacity now.
Q = m c Θ
110cal = 1kg × c × (70 - 60 ) °C
110cal= 0.1kg × c × 10°C
110 = 1 c
Divide both sides by 1.
c = 110 cal kg⁻¹°C⁻¹
What is the mass of an object if a force of 48 Newtons produces an acceleration of 6 m/s2?
Answers
Answer:
m = 8 kg
Explanation:
According to Newton's second law of motion, F = ma.
Solving for m using algebra:
m = F ÷ a
m = 48 N ÷ 6 m/s² = 8 kg
How much force is need
to accelerate a 50 kg
object 20 m/s2?
Answers
Answer:
F = 1000 N
Explanation: When calculating force, F=ma.
So...
F = (50)(20)
1000 = (50)(20)
