Answer:
1419.01436 N
Explanation:
t = Time taken
u = Initial velocity
v = Final velocity
s = Displacement
a = Acceleration

The force on the car

Magnitude of the horizontal net force that is required to bring the car to a halt is 1419.01436 N
B; to produce a hypothesis.
Answer:
The range of the projectile is 66.7 meters.
Explanation:
The range of a projectile is given by the following expression as :
..............(1)



The range can be calculated using equation (1). Putting the values of all parameters we get :

R = 66.7 meters
So, the range of the projectile is 66.7 meters. Hence, this is the required solution.
Ability to memorize and regurgitate information on tests is the skill that can’t help a person to thrive today in this modern 21st century.
Answer: Option D
<u>Explanation:</u>
Thriving in this modern 21st century is not as easy as it used to be in the early 20th and 19th centuries. So there is a need to develop skills like implementing one's knowledge to real-world structures which will sure help a person to understand and explore more.
Statement B also will sure be helpful to survive in modern society and a person can also improve his/her critical thinking, problem solving and other skills to thrive through this century.
But even though memorizing and regurgitating information can help you get good grade it will never be that helpful in other ways, So option D can be concluded as the right answer.
Answer:
The charge on point A is
= 2.4 ×
C
The charge on point B is
= 1.2 ×
C
Explanation:
Given data
Distance (r) = 0.19 m
Magnitude of the charge on A is twice that of the charge on B i.e.

F = 46 N
We know that force between the charges is given by


= 1.2 ×
C
= 2 ×
= 2 × 1.2 × 
= 2.4 ×
C
Therefore the charge on point A is
= 2.4 ×
C
The charge on point B is
= 1.2 ×
C
