The answer is D
The reason being because the singular replacement has the first letter of each side swap
For Example: A+BC —> B+AC
The car A and car B are travelling at different speeds. The car that has a greater acceleration is car B.
<h3>What is acceleration?</h3>
Acceleration is defined as the rate change of velocity with time.
acceleration a = (Δv) / (Δt)
Car A is traveling with a constant velocity of 18 [m/s]. The initial and final velocity is same. So, the acceleration is given by
a = (18 -18)/ t
a = 0 m/s²
Car B speeds up from 0 [m/s] to 10 [m/s] in 4 seconds. The acceleration is
a = (10 -0)/ 4
a = 2.5 m/s²
Thus, the car B has greater acceleration.

D) activation gate - opens during depolarization
Part 1. F= m*a
M=12kg
A= 3 m/s^2
So F = 12kg * 3 m/s^2 which means
F=36 Newton’s
Part 2. F=12000N
M= F/A
A=4 m/s^2
So M= 12000N / 4 m/s^2
Which means M=3000 kg
Answer:
the time required is 0.886 seconds
Explanation:
The computation is shown below:
As we know that the content of the chemical energy that has a calorific value of hydrogen is 141790 kJ /kg
And, the total energy stores is 100,000 kg
Now
E = 141790 × 100,000 kJ
= 14.179 TJ
The time would be
T = E ÷ P
= 14.179 ÷ 16
= 0.886 sec
hence the time required is 0.886 seconds
