Answer:
The show with 20 N force will accelerate more than the show with 10 N force, because 20 N force is greater than 10 N force.
Explanation:
From Newton's second law of motion, acceleration is the ratio of applied to mass of the object.
Acceleration is directly proportional to an applied force. At a constant mass, acceleration increases with an increase in the applied force.
Therefore, the show with 20 N force will accelerate more than the show with 10 N force, because 20 N force is greater than 10 N force.

Explanation:
Given that,
Initial speed of the missile u = 0
Final speed of the missile, v = 4.5 km/s = 4500 m/s
Time taken by the missile, t = 90 s
Let a is the acceleration of the sports car. It can be calculated using first equation of motion as :
Value of g,
So, the acceleration of the missile is . Hence, this is required solution.
Answer: 1.82
Explanation:
Given that the
Object distance U = 24.8 cm
Focal length f = 16.0 cm
Let us first calculate the image distance by using the formula
1/f = 1/u + 1/v
Substitute f and u into the formula
1/16 = 1/24.8 + 1/v
Make 1/v the subject of formula
1/v = 1/16 - 1/24.8
1/v = 0.0625 - 0.04032258
1/v = 0.022177419
Find the reciprocal of both sides
V = 45.09 cm
Magnification = image distance ÷ object distance
Magnification = 45.09/24.8
Magnification = 1.818
Therefore, magnification of the image is 1.82 approximately
Answer:
20.The first factor is the amount of charge on each object. The greater the charge, the greater the electric force. The second factor is the distance between the charges. The closer together the charges are, the greater the electric force is
