Ignoring air resistance, the bullet's horizontal velocity is constant:
In 1.3 seconds, we can expect it to travel
Answer:
420J
Explanation:
Power is the time rate of change in energy. Power is the ratio of energy to time. The S.I unit of power is in watts.
Given that the flash lasts for 1/675 s, power output is 2.7 * 10⁵ W. Hence:
Power = Energy / time
Substituting:
2.7 * 10⁵ W = Energy / (1/675)
Energy = 2.7 * 10⁵ W * 1/675 = 400J
Therefore the energy emitted as light is 400J.
Since the conversion of electric energy to light is 95% efficient, hence the energy stored as electrical energy is:
Energy(capacitor) = 5% of 400J + 400J = 0.05*400 + 400
Energy(capacitor) = 420J

The power that must be delivered to the object by the force is 50 W
Power is defined as the rate of doing work. The power of an object in relation to the force and velocity is given by the following equation:
Power (P) = Force (F) × velocity (v)
P = F × v
From the question given above, the following data were obtained:
- Force (F) = 10 N
- Velocity (v) = 5 m/s
- Power (P) =?
P = F × v
P = 10 × 5
<h3>P = 50 W </h3>
Thus, the power that must be delivered to the object by the force is 50 W

Answer:
C: Variation in the value of g as the pendulum bob moves along its arc.
Explanation:
The formula for period of a simple pendulum is given by;
T = 2π√(L/g)
Where;
L is length
g is acceleration due to gravity
Now, from this period equation, it is clear that the only thing that can affect the period of a simple pendulum are changes to its length and acceleration due to gravity.
Looking at the options, the only one that talks about either the length or gravity as being potential causes of the error is option C
