Answer: The reactions are controlled to regulate energy output
Explanation:
Nuclear energy is produced when either two nuclei fuse to produce larger nucleus or a bigger nuclei splits into two smaller nucleus.
Uranium easily splits to produce nuclear energy. The reactions are controlled and energy output can be regulated. Nuclear energy in abundant yet controlled amount is available. Nuclear energy is mostly used in steam turbines to produce electricity.
Answer:
Tectonic Plate Movement
Explanation:
Each continent and ocean sits on its own tectonic plate which floats on the Earths upper mantle. They move very little over time.
Non metal ions gain electrons to become negative ions
V: there would be no seasons and humanity would suffer
The question involves the knowledge of kinematics and dynamics. The answers are;
a) Time taken to stop the car = 10 s
b) The operation that slows the car is Friction
c) The size of the force = 1200 N
<h3>
What is Deceleration ?</h3>
Deceleration is the opposite of acceleration. When an object is going to rest, it will be decelerating and the final velocity will be equal to zero.
Given that the driver of a car moving at 15 m/s along a straight level road applies the brakes. The car decelerates at a steady rate of 3/2 m/s²
a) How long does the car take to stop can be found by using the formula
v = u - at
Where
Substitute all the parameters into the formula
0 = 15 - 1.5t
1.5t = 15
t = 15/1.5
t = 10 s
b) The description of the operation that slows the car down after the brake pedal is pressed is simply friction.
c) If the mass of the car is 800. The size of the force slowing the car down will be F = ma
F = 800 × 1.5
F = 1200 N
Therefore, the time taken to stop the car is 10 s and the force slowing the car down is 1200 N
