Answer:
See explanation below.
Explanation:
The internal energy (kinetic energy) of the milk particles increases thus warming the milk up, while the internal energy of the coffee particles reduce their initial average speed as they are imparting energy to the slow milk particles.
Answer:
Electric field intensity is the force experienced by a test charge q in a electric field E.
Answer:
s = 307.34 m
Explanation:
In order to find the distance covered by the dragster during the given time, we will use second equation of motion. The second equation of motion is written as follows:
s = Vi t + (0.5)at²
where,
s = distance covered by the dragster = ?
Vi = Initial Velocity = 0 m/s
t = time interval = 3.97 s
a = acceleration = 39 m/s²
Therefore,
s = (0 m/s)(3.97 s) + (0.5)(39 m/s²)(3.97 s)²
<u>s = 307.34 m</u>
Answer:
The velocity of the ball at it's highest point is zero.
Explanation:
When we toss a ball upwards as we know that it's motion is an uniformly accelerated motion with acceleration =
in the downward direction.
Hence as we throw the ball upwards it's speed will go on decreasing as it gains height. The ball will stop gaining height when it's velocity becomes zero and the ball starts to descend again towards earth.
If the ball is tossed at an angle with the horizontal in that case it's velocity at the top most point will not be zero but in our case since the ball is tossed vertically it's velocity at the topmost point will become zero.
