A geyser is actually a devise that coverts electrical energy
into heat energy for heating up water. The heating element that is inside the
geyser actually gets heated up and then in turn it heats the water in contact
with it within the geyser. There is also a thermostat device within the geyser
that cuts off the heating when the water temperature reaches the desired level.
This helps in stopping of electrical energy loss. One inlet brings in cold
water while another outlet gets rid of the hot water. When the temperature of
the water falls below the desired level the heating is again started by the
thermostat.
Explanation:
after 5 seconds, the velocity is (5s)(3m/s²) = 15m/s
The displacement after 5s is
x=vo + (1/2)at²
x = 0 + (1/2)(3m/s²)(5s)(5s)
x= 37.5 m
Answer:
The strength of gravity decreases.
An example of that would be if you were in space; you float around because there's no gravity.
The distance covered by the acorn is 3.136 m.
<u>Explanation:</u>
The time taken for the acorn to hit the ground is 0.8 s. As it is a free fall, the acorn will be completely under the influence of gravity. So the acceleration will be acceleration due to gravity.
Then using the second law of equation,
Since the initial velocity and time is zero, then the time taken to reach the ground is stated as 0.8 s, so
So the distance covered by the acorn is 3.136 m.
Answer:
C
Explanation:
Angular momentum is the product of moment of inertia and angular velocity.
L = I × ω
Since the planet follows a stable circular orbit, I and ω are constant and non-zero. Therefore, the angular momentum is constant and non-zero.
