How do you determine the wattage capacity needed by a power supply?

1 answer:

6 0

We could use the formula for the Power supply in order to find the wattage capacity and it would be:

P = V²/R or P = V * I

Hope this helps!

a 150 N force is used to pull a wooden box across a wooden surface at a constant velocity. what is the mass of the box?

IRINA_888 [86]

Answer:

The mass of the box:

m = 60 kg

Explanation:

Given:

F = 150 N

g = 10 m/s²

_________

m - ?

Coefficient of friction wood on wood:

μ = 0.25

Friction force:

F₁ = μ*m*g

Newton's Third Law:

F = F₁

F = μ*m*g

The mass of the box:

m = F / ( μ*g) = 150 / (0.25*10) = 60 kg

A student applies a 10 N force to a wood block with a mass of 5 kg. The block is pushed across four different surfaces. The acce

Furkat [3]

The complete question is as follows: A student is subjected to a reaction force of 10 N northward from a 5 kg block while pushing the block over a smooth, level surface. Ignoring friction, what is the acceleration of the block?

Answer: The acceleration of the block is $2 m/s^{2}$ .

Explanation:

Given: Force = 10 N

Mass = 5 kg

It is known that force applied on an object is the product of mass and acceleration.

Mathematically, $F = m \times a$

where,

F = force

m = mass

a = acceleration

Substitute the values into above formula as follows.

$F = m \times a\\10 N = 5 kg \times a\\a = \frac{10}{5}\\= 2 m/s^{2}$

Thus, we can conclude that the acceleration of block is $2 m/s^{2}$ .
