Position and momentum.
This is Heisenberg's Uncertainty Principle:
Δx Δp ≥ h ÷ 4π, where Δx is the change in position, Δp is the change in momentum, and h is Planck's Constant.
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
Answer:
The free fall acceleration on the surface of this planet is 4.35 m/s²
Explanation:
Given that,
Mass of planet
Radius of planet
We need to calculate the free fall acceleration on the surface of this planet
Using formula of gravity
Where, = mass of planet
= radius of plane
Put the value into the formula
Hence, The free fall acceleration on the surface of this planet is 4.35 m/s²
Answer:
the work done on the car is 7,500 J.
Explanation:
Given;
distance traveled by the car, d = 150 m
applied force, F = 50 N
The work done on the car is calculated as;
W = F x d
W = 50 N x 150 m
W = 7,500 J
Therefore, the work done on the car is 7,500 J.
Answer:
As you throw the ball up into the air, its direction is up, but the speed decreases due to the pull of gravity. The ball slows down, and at the very top of its flight, its velocity at that instant is zero.
