Define the relationship between force acceleration and mass

1 answer:

4 0

Force is mass times acceleration. This means an object with a larger mass needs a stronger force to be moved along at the same acceleration as an object with a small mass

If you exert a force of 700 N to walk 6m up a flight of stairs in 6s how much power do you lose?

SashulF [63]

Answer:

700 watts

Explanation:

From the question, it is given that;

Force = 700N

Distance = 6m

Time = 6s

<u>First step:</u> we derive the formula that relates Power, distance and time, from first principle

$Power = \frac{Energy}{Time}$

But Energy is Force X Distance

$Power = \frac{Force X Distance}{Time}$

$Power = \frac{(700) X (6)}{6}$

Power = 700 watts

The power you will lose after walking the stairs is 700 watts

Determine the direction of the force (if any) that will act on the charge in each of the following situations. A positive charge

NeTakaya

Answer:

a) F on the right , b) F up , c) Force to the left , d) Force down , e) Force towards the screen , f) Force is zero

Explanation:

The equations for the forces are

Electric

F = q E

Magnetic

F = q v x B

The Bold are vectors, the charges are positive

Let's apply these equation to the proposed situations

a) as the load is positive the force goes in the direction of the field

F on the right

b) as the load is negative the force goes in the opposite direction to the field

F is up

c) positive charge with speed down and magnetic field out of the screen.

For this part we will use the right hand rule. The thumb is in the direction of the speed, the fingers extended in the direction of the magnetic field and the palm is in the direction of the force for a positive charge

Force to the left

d) negative charge, speed to the right magnetic field between the screen

The force has direction

Force down

e) positive charge, electric field towards the screen.

Force in the direction of the field

Force towards the screen

.f) negative charge, speed to the right, magnetic field to the right

The vector product is zero,

Force is zero

A labor push a crate through 12m and 720 J of work .The magnitude of force was

Harrizon [31]

Answer:

Explanation:

The magnitude of the force can be found by using the formula

$f = \frac{w}{d} \\$

w is the workdone

d is the distance

From the question we have

$f = \frac{720}{12} = 60 \\$

We have the final answer as

Hope this helps you

The velocity of an object is the distance it travels per unit time. Suppose the velocity of a gilding bird is measured to be 52.

Elanso [62]

Answer:

$d=7.115s$

Explanation:

What problem says can be written mathematically as:

$v=\frac{d}{t}$

Where:

$v=Velocity\\t=Time\\d=Distance$

The problem itself it's really simple, we only need to replace the data provided in the previous equation, but first, let's convert the units of the velocity from cm/s to m/s because we have to work with the same units and working in meters is the most apropiate action, because is the base unit of length in the International System of Units:

$52\frac{cm}{s} *\frac{1m}{100cm} =0.52\frac{m}{s}$

Now, we can replace the data in the equation and find the time it will take the bird to travel 3.7 m:

$0.52=\frac{3.7}{t}$

Solving for t, multiplying by t both sides, and dividing by 0.52 both sides:

$t=\frac{3.7}{0.52} =7.115384615s\approx7.115s$
