ANSWER:
a. Velocity decreased
STEP-BY-STEP EXPLANATION:
If the person inside the bus experiences a forward movement, this means that the bus is braking, since by action-reaction to compensate for the movement, the body moves forward.
When braking, it means that there is a decrease in speed, therefore, the correct answer is a. Velocity decreased
Answer:
1.The temperature of each sample will increase by the same amount
Explanation:
This is because, since their specific heat capacities are the same and we have the same mass of each substance, and the same amount of energy due to heat flow is supplied to both the glass and brick at room temperature, their temperatures would thereby increase by the same amount.
This is shown by the calculation below
Q = mcΔT
ΔT = Q/mc where ΔT = temperature change, Q = amount of heat, m = mass of substance and c = specific heat capacity of substance.
Since Q, m and c are the same for both substances, thus ΔT will be the same.
So, the temperature of each sample will increase by the same amount
