Answer:
Force = 24.5 Newton
Explanation:
Given the following data;
Mass = 3.50 kg
Initial velocity, u = 3 m/s
Final velocity, v = 17 m/s
Time, t = 2 seconds
To find the force;
First of all, we would determine the acceleration of the object using the formula;
Acceleration = (v - u)/t
Acceleration = (17 - 3)/2
Acceleration = 14/2
Acceleration = 7 m/s²
Now, we can find the force using the formula;
Force = mass * acceleration
Force = 3.5 * 7
Force = 24.5 Newton
N, or Neutons are a common way to measure force
Answer:
Explanation:
The wording on some of these choices is very strange; I'm not sure exactly what they are stating. First of all, A. is definitely a choice because if both the charges were opposite, they would be attracted to one another as opposed to be repelled away from one another, as they are when they are both positive. What happens is that the charges go OUT from the positive charge and INTO the negative; so as far as the field lines around both charges would change direction...no; only the direction of the field lines would change on the positive charge (which is the one on the left). In that space where D is filled in by the field lines going OUT of the positive charge and INTO the negative one, the lines there are naturally closer together, and that is the point where the charge is the greatest. So if that is what is meant by the field lines getting closer together, then yes, they do. As far as choice D. again the field lines on the negative charge don't change, only the ones on the positive charge change.
The answer is Anxiety. Hope this helps.
Answer:
continually change by the same amount each second
Explanation:
We all are aware with the fact that a car speeds is increased when we put our feet on the accelerator. The rate at which the particle's velocity change with time is called its acceleration. If the particle's velocity changes with constant rate, then its rate is called the constant acceleration.
Since the basic units are meter and seconds. And the SI unit of velocity is 
and acceleration's SI unit is 
For example if the velocity is change from 2 to 4 m/s in 1 sec its acceleration is 
and again its velocity is change with 4 m/s to 6 m/s will again give constant acceleration in 1 s is .
