Children learn to resolve conflicts from surrounding adults.

sergij07 [2.7K]

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.
Children are the best imitators of the adult around them. From all the activities adults perform around them, they learn that and apply in their life.
So it is always best to take care of our activities that we perform in front of our children.

the olympic swimmer swims to the end of the 50 m pool and back 4 times. calculate the distance covered.

Ludmilka [50]

Answer:

400 m

Explanation:

The swimmer swims 50 meters to one end of the pool but has to swim back therefore you double 50 which would be 100 meters. Then you have to multiply 100 by 4 since the swimmer did it 4 times.

Finish A 16 N force is applied to an object and 96 J of work is done. How far was the object moved?

Lina20 [59]

Answer:

$\boxed {\boxed {\sf 6 \ meters}}$

Explanation:

Work is the product of force and distance.

$W=F*d$

We know that 96 Joules of work were done and a 16 Newton force was applied to the object.

W= 96 J
F= 16 N

Substitute the values into the formula.

$96 \ J= 16 \ N * d$

First, let's convert the units. This will make cancelling units easier later in the problem. 1 Joule (J) is equal to 1 Newton meter (N*m), so the work of 96 Joules equals 96 Newton meters.

$96 \ N*m= 16 \ N * d$

Now, solve for distance by isolating the variable, d. It is being multiplied by 16 Newtons and the inverse of multiplication is division. Divide both sides of the equation by 16 N.

$\frac {96 \ N*m}{16 \ N}= \frac{16 \ N *d}{16 \ N}$
