A dump truck going 70 mph
Explanation:
hope it helps you
Correct answer choice is :
C) Force
Explanation:
In physics, a force is any cooperation that, when unrestricted, will vary the motion of an object. A force can create an object with mass to alter its velocity to accelerate. Force can also be defined intuitively as a push or a pull. A force acting on an object may create the object to alter shape, to start moving, to stop moving, to stimulate or decelerate. When two objects communicate with each other they exert a force on each other, the forces are just in size but different in direction.
Answer:5.45X10^3m
Explanation:So use the formula,v= fλ
3X10^8=5.5X10^4λ what Im saying is divide both and u should get 5454.54m but do sig figs to get answer
Acceleration is the rate of change of velocity per unit of time.
Answer:
Charge of particle 2, 
Explanation:
Given that,
Charge 1, 
The distance between charges, r = 0.241 m
Force experienced by particle 1, F = 3.44 N
We need to find the magnitude of electric charge 2. It can be calculated using formula of electrostatic force. It is given by :
or
So, the magnitude of electric charge 2 is . Since, the force is attractive then the magnitude of charge 2 must be negative.
