Answer:
4960 N
Explanation:
First, find the acceleration.
Given:
v₀ = 6.33 m/s
v = 2.38 m/s
Δx = 4.20 m
Find: a
v² = v₀² + 2aΔx
(2.38 m/s)² = (6.33 m/s)² + 2a (4.20 m)
a = -4.10 m/s²
Next, find the force.
F = ma
F = (1210 kg) (-4.10 m/s²)
F = -4960 N
The magnitude of the force is 4960 N.
Answer:
43.96 L
Explanation:
We are given that
We know that
Substitute the values
Hence, the volume of balloon at -14.8 degree Celsius=43.96 L
Answer:
Temperature
Explanation:
The heat flows from high temperature to low temperature.So we can say that temperature is the property that decide the direction of heat flow.Like in the electric system current flow high voltage to low voltage ,so we can say that voltage is the property which determine the direction of current flow.
So the answer is Temperature.
Answer:
B. Nuclear to Electrical
Explanation:
Atoms are split at power plants to create electricity. The energy conversion in this process is from nuclear to electrical energy.
- When atoms are split, nuclear energy is released.
- Some part of the mass of the atom is converted to energy.
- The nuclear energy released is expressed as heat energy.
- This energy is used to heat water in boilers when produces steam that are used to drive the movement of turbines.
- This in turn generates electricity.
