Answer:
1. Energy = 2880 Joules.
2. Energy = 60 Joules.
3. Quantity of charge = 120 Coulombs.
Explanation:
Given the following data;
1. Voltage = 12 Volts
Current = 0.5 Amps
Time, t = 8 mins to seconds = 8 * 60 = 480 seconds
To find the energy;
Power = current * voltage
Power = 12 * 0.5
Power = 6 Watts
Next, we find the energy transferred;
Energy = power * time
Energy = 6 * 480
Energy = 2880 Joules
2. Charge, Q = 4 coulombs
Potential difference, p.d = 15V
To find the total energy transferred;
Energy = Q * p.d
Energy = 4 * 15
Energy = 60 Joules
3. Voltage = 6 Volts
Current = 1 Amps
Time = 2 minutes to seconds = 2 * 60 = 120 seconds
To find the quantity of charge;
Quantity of charge = current * time
Quantity of charge = 1 * 120
Quantity of charge = 120 Coulombs
I believe the answer is A.
Hope This Helps! Have A Nice Day!!
Answer:
The acceleration would double
Explanation:
Assuming the same box and spring, the maximum acceleration is proportional to amplitude. When the amplitude doubles, the acceleration would double.
__
A spring is generally considered to have a linear force vs. distance characteristic. Hence, doubling the distance doubles the force. The acceleration is proportional to the force.
the greater the <u>mass</u> of an object the more force is needed to cause acceleration
Answer:
They travel slower than P waves.
They result in much ground motion.
Explanation:
There are three types of seismic waves: P waves, S waves and Surface waves.
P wave are primary waves which require medium to travel. These are fastest waves. S waves are the secondary waves. These are transverse waves. S waves move slower than P waves. Both of these waves can travel through the inner layers of Earth.
Surface waves travel near the surface or above the surface of the Earth. These travel slower than S waves and P waves but have large amplitudes which could much ground motion and cause huge destruction.
Hence, the statements describe the surface waves:
They travel slower than P waves.
They result in much ground motion.
