Answer:

Explanation:
We are asked to find the mass of a cabinet, given the force and acceleration. According to Newton's Second Law of Motion, force is the product of mass and acceleration. The formula for this is:

The force is 200 Newtons, but we should convert the units to make unit cancellation easier. 1 Newton is equal to 1 kilogram meter per second squared, so the force of 200 Newtons is 200 kilogram meters per second squared. 
The mass is unknown and the acceleration is 4 meters per second per second or 4 meters per second squared.
Substitute the values into the formula.

We are solving for the mass, m, so we must isolate the variable. It is being multiplied by 4 meters per second squared. The inverse operation of multiplication is division. Divide both sides by 4 m/s²


The units of meters per second squared cancel.


The mass of the cabinet is <u>50 kilograms.</u>
 
        
             
        
        
        
Answer:
Explanation:
One charge is situated at x = 1.95 m . Second charge is situated at y = 1.00 m 
These two charges are situated outside sphere as it has radius of .365 m with center at origin. So charge inside sphere = zero. 
Applying Gauss's theorem 
Flux through spherical surface = charge inside sphere / ε₀
= 0 / ε₀
= 0 Ans .

Answer:
V=21.0211m/s
Explanation:
Use V=vi+at
So, V=17.46m/s+(1.49m/ )(2.39s)= 21.0211m/s
)(2.39s)= 21.0211m/s
