False- the potential energy is force*distance and force is mass*acceleration so if there’s more mass, there’s more force, so there’s more potential energy
Hope that helps :)
The solution is impossible because when the apply the right equation for electrical power, the current obtained is 0.83 A and not 11.4 A
<h3>What is power?</h3>
This is defined as the rate in which energy is consumed. Electrical power is expressed mathematically as:
Power (P) = voltage (V) × current (I)
P = IV
With above formula, we can obtain the current drawn by the bulb. Details below
<h3>How to determine the current flowing in the circuit</h3>
From the question given, the following data were obtained:
- Power (P) = 100 W
- Voltage (V) = 120 V
- Current (I) =?
P = IV
Divide both sides by V
I = P / V
I = 100 / 120
I = 0.83 A
Thus, we can see that the current drawn by the bulb is 0.83 A and not 11.4 A
From the above, we can see clearly why the inquisitive physics student' calculation is wrong.

Answer:
The value of the acceleration of gravity of the Unknown Planet = 1.14
Explanation:
length of the pendulum (L)= 1.15 m
Time period (T)= 6.29 seconds
We know that time period of a simple pendulum is given by
⇒ T = 2 ×
put the values in the above formula we get
⇒ T = 2 ×
⇒ 6.29 = 2 ×
By solving the above equation we get
⇒ g = 1.14
This is the value of the acceleration of gravity of the Unknown Planet.
Answer:
63393.8 lbfeet/sec^2
Explanation:
Recall that the weight density of water is 62.5 lb/ft3
F = PA P = hρg = h x 62.5 x 32.2 A = 5 x dh force= integral of (hρg3 x dy) // 3 is width of plane force= integral of ( 62.5 x 32.2 x 3 x hdh) from 2 to 5 force= 62.5 x 32.2 x 3 x (5^2-2^2)/2 = 63393.8 lbfeet/sec^2
