Answer:
C) the equation consists of two factors:
work = force * distance
W = F · S
Answer:
(a) How much heat transfer is required to raise the temperature of a 0.750-kg aluminum pot containing 2.50 kg of water from 30.0 °C to the boiling point and then boil away 0.750 kg of water?
(b) How long does this take if the rate of heat transfer is 500 W? 1 watt = 1 joule / second (1W = 1 J/s).
(a) The total heat required is 2.47 × 10 ⁶ J
(b) It takes 82.3 min

Answer:
When we increase the applied force (push harder), the frictional force will also increase until it reaches a maximum value. When the applied force is larger than the maximum force of static friction the object will move. ... For kinetic friction the value remains the same regardless of the magnitude of the applied force.
Answer:
Distance travelled, d = 0.21 m
Explanation:
It is given that,
Initial velocity of electron, u = 500,000 m/s
Acceleration of the electron, a = 500,000,000,000 m/s²
Final velocity of the electron, v = 675,000 m/s
We need to find the distance travelled by the electron. Let distance travelled is s. Using third equation of motion as :
s = 0.205 m
or
s = 0.21 m
So, the electron will travel a distance of 0.21 meters. Hence, this is the required solution.
