Answer:
The acceleration of a car would be:
m/s²
Explanation:
Given
Initial velocity =
m/s
Final velocity =
m/s
Time elapsed =
s
To determine
We need to determine the acceleration of a car.
We know that acceleration is basically the rate of change in velocity over time.
Thus,
We can determine the acceleration using the formula

where
is the acceleration
is the initial velocity
is the final velocity
is time elapsed
now substituting the values
,
, and
in the formula



m/s²
Therefore, the acceleration of a car would be:
m/s²
The efficiency of a machine is the ratio between the output power and the power in input:

in our problem, the output power is 3760 W while the input power is 4000 W, so the efficiency is

So the efficiency of the machine is 94%.
Answer:
35 m/s^2
Explanation:
Decceleration = change in velocity / change in time
= ( 70 m/s ) / 2 seconds = 35 m/s^2
DEcceleration = 35 m/s^2
Jason's speed changes by - 35 m/s^2
Sustainable buildings are generally less expensive over the lifetime of the building, due to lower energy costs in production of the materials and lower energy bills. Option A is correct.
<h3>What is sustainable buildings? </h3>
Sustainable buildings refer to both a structure and the implementation of environmentally responsible and resource-efficient methods.
Sustainable buildings are generally less expensive over the lifetime of the building, due to lower energy costs in production of the materials and lower energy bills,
Hence,option A is correct.

Answer:
It will produce a stronger magnetic field.
Explanation:
Ampere’s law states the magnetic field of a solenoid is directly proportional to the current supplied.
