Answer:
A pushing force example could be a button, like on a keyboard.
Another example would be a piston.
An example of a pulling force could be a lever.
Another example could be rope.
Hope this helps! c:
<span>A battery creates a potential difference, or voltage, which is really just storing electrical potential energy just as a pump would by moving water up against gravity, thereby storing gravitational potential energy. To complete the analogy, as current flows through the circuit, this potential energy is released and can be used by the components in the circuit. This is the same as water falling back down and turning some wheel or turbine and converting its gravitational potential energy into mechanical energy.</span>
Answer:
The initial mass of the rocket is 526.2 kg.
Explanation:
Given that,
Final speed = 105 m/s
Time = 18.0 s
Exhaust initial speed = 1200 m/s
Mass of burned fuel = 110 kg
We need to calculate the initial mass
The velocity change of rocket under gravity is defined as,
....(I)
We know that,
Put the value of m in equation (I)
Hence, The initial mass of the rocket is 526.2 kg.
