Answer:
Explanation:
Given that
There's a change in friction from 440 kJ to 110 kJ
This change is as a result of conversion of energy. The energy of the car system converted the mechanical energy in it, into a corresponding heat energy. During the course of this conversion, is where a whopping 330 kJ of energy went missing.
The 330 kJ of energy was lost as a result of the conversion of mechanical energy into heat energy by the use of friction.
<h2>A. 2.5 kg.m/s</h2>
this is my answer sure po ako n tama iyan
Answer & Explanation:
Crashing into the asteroid would cause the satellite to slow down, stop, or reverse direction, because it is a force in the opposite direction to the satellite's motion. Whichever crash was a stronger force would cause it to change motion more. It takes a stronger force to change the velocity of a more massive object.
Answer:
Induced emf in the loop is 0.02208 volt.
Induced current in the loop is 0.0368 A.
Explanation:
Given that,
Area of the single loop,
The initial value of uniform magnetic field, B = 3.8 T
The magnetic field is decreasing at a constant rate,
(a) The induced emf in the loop is given by the rate of change of magnetic flux.
(b) Resistance of the loop is 0.6 ohms. Let I is the current induced in the loop. Using Ohm's law :
Hence, this is the required solution.
Answer:
t = 1023.9 seconds
Explanation:
Given that,
The average velocity of a Mustang, v = 33m/s
Distance, d = 21 miles = 33789 m
Let the driver takes t seconds. So,
Speed = distance/time
So, it will take 1023.9 seconds to complete the course.
