Answer:

Force, F = 10.5 N

Explanation:

Given that,

Mass of the soccer ball, m = 0.42 kg

Acceleration of the soccer ball, $a=25\ m/s^2$

Let F is the force acting on the soccer ball. It can be calculated using second law of motion. Its mathematical form is given by :

$F=m\times a$

$F=0.42\times 25$

F = 10.5 N

So, the force acting on the soccer ball is 10.5 N. Hence, this is the required solution.

It is definitely letter D. <span>A1 and B1 are like poles, but there is not enough information to tell whether they are north poles or south poles.

A1 and B1 is either both north poles or both south poles. Repulsion of both magnets says it all--like poles always repel while opposite poles always attract. Thus, the best conclusion to this would be choice D.</span>

Answer:

20.45%

Explanation:

The probability that the student got a B is

$\frac{total\#of\text{ students that got B}}{\text{total students }}\times100\%$

Now, how many students are there in total?

The answer is

$10+3+16+4+6+5=44\; \text{students}$

How many students got a B?

The answer is

$3+6=9\; \text{students}$

therefore, the probability that the student has got a B is

$\frac{9\text{ students }}{44\text{ students }}\times100\%=20.45\%$

Hence, the probability that a student has got a B is 20.45%

You use a pulley system to lift a car engine. You apply a force of 120n and the pulley pulls on the engine with a force of 1050n

Savatey [412]

Given,

Effort force = 120 N

Load force= 1050 N

Mechanical advantage of a pulley is given by the ratio of load force to the effort force.

$M.A=\frac{Load force}{Effort force}$

$=\frac{1050}{120}$

$=8.75$

Therefore, the mechanical advantage of the given pulley is 8.75.

Red Riding Hood sat down to rest and placed her 1.20-kg basket of goodies beside her. A wolf came along, spotted the basket, and

Answer:

117.6°

Explanation:

The vertical component of a force directed at some angle α from the vertical is ...

F·cos(α)

We want the vertical components of the wolf's force (Fw) and Red's force (Fr) to total zero. So for some angle from vertical α, Red's force will satisfy ...

Fw·cos(25°) + Fr·cos(α) = 0

cos(α) = -Fw/Fr·cos(25°) ≈ -(6.4 N)/(12.5 N)·0.906308 ≈ -0.464030

α ≈ arccos(-0.464030) ≈ 117.6°

Red was pulling at an angle of about 117.6° from the vertical.

_____

<em>Additional comment</em>

That's about 27.6° below the horizontal.
