Answer:
Explanation:
We shall apply concept of impulse
Impulse = Force x time
= Force x 2 x 10⁻³ N.s
impulse = change in momentum
change in momentum
= .4 x 4 - ( - .4 x 2 )
= 2.4
Force x 2 x 10⁻³ = 2.4
Force = 2.4 / 2 x 10⁻³
= 1.2 x 10³ N .
average magnitude of the force exerted by floor = 1.2 x 10³ N
If R be reaction force by earth
R - mg = 1.2 x 10³
R = 1.2 x 10³ + mg
= 1200 + .4 x 9.8
= 1200 +3.92
= 1203 .92 N .
Explanation:
I think the total resistance of the resistors is 1 ohm . it is also known as equivalent resistance.
hope it helps.
Answer:
It is true that children learn to resolve conflicts from surrounding adults.
Explanation:
- The environment where the children are raised reflects their decision making abilities and conflicts handling power.
