The force the same object will exert if it accelerates at a rate of 7 m/s² is 35N
From the question,
We are to determine the force the object will exert.
From the information,
Newton’s Second Law of Motion states that the acceleration of an object is directly proportional to the force exerted on the object
Let acceleration be a
and
Force be F
Then we can write that,
F ∝ a
Then,
Introducing the constant, mass, m
We get
F = ma
Now, we will determine the mass of the object
F = 15 N
a = 3 m/s²
Putting the parameters into the formula, we get
15 = m × 3
∴ m = 15 ÷ 3
m = 5 kg
The mass of the object is 5 kg.
Now, to determine the force the same object will exert if it accelerates at a rate of 7 m/s²
That is,
a = 7 m/s²
and
m = 5 kg
Putting the parameters into the formula, we get
F = 5 × 7
F = 35 N
Hence, the force the same object will exert if it accelerates at a rate of 7 m/s² is 35N

Two pounds is two pounds. It is a trick question making you focus more on the material, rather than the main point at hand. TWO pounds is TWO pounds, regardless of material.
Answer:
(1) 97
(2) 385
(3) 9604
Step-by-step explanation:
The (1 - <em>α</em>) % confidence interval for population proportion is:
The margin of error in this interval is:
The formula to compute the sample size is:
(1)
Given:
*Use the <em>z</em>-table for the critical value.
Compute the value of <em>n</em> as follows:
Thus, the minimum sample size required is 97.
(2)
Given:
*Use the <em>z</em>-table for the critical value.
Compute the value of <em>n</em> as follows:
Thus, the minimum sample size required is 385.
(3)
Given:
*Use the <em>z</em>-table for the critical value.
Compute the value of <em>n</em> as follows:
Thus, the minimum sample size required is 9604.
