For the gravitational force the formula<span> is P.E. = mgh, where m is the mass in kilograms, g is the acceleration due to gravity (9.8 m / s</span>2<span> at the surface of the earth) and h is the </span>height<span> in meters. Notice that gravitational potential </span>energy<span> has the same units as </span>kinetic energy, kg m2<span> / s</span>2<span>.

HOPE THIS HELPS</span>

If you use a force of 90 N to pick up a 10 pound bag of charcoal, what is the acceleration?

hjlf

Answer:

9ms^2

Explanation:

since ,Force=mass*acceleration

then, acceleration=force/mass

and, Force=90N

Mass=10pound

therefore, acceleration=90/10

=9ms^2

While a block slides forward 1.35 m, a force pulls back at a 135 direction, doing -17.8 J of work. what is the magnitude of the

Verdich [7]

The magnitude of the force is 18.6 N

Explanation:

The work done by a force on an object is given by

$W=Fd cos \theta$

where

F is the magnitude of the force

d is the displacement of the object

$\theta$ is the angle between the direction of the force and of the displacement

For the block in this problem, we have

$W=-17.8 J$ is the work done

d = 1.35 m is the displacement of the block

$\theta=135^{\circ}$ is the angle between the force and the displacement

Solving for F, we find the magnitude of the force:

$F=\frac{W}{d cos \theta}=\frac{-17.8}{(1.35)(cos 135)}=18.6 N$

Is a fault or igneous intrusion that cuts across rock layers younger or older than the rocks it disrupts?

Ksju [112]

It is younger because there had to be rock layers already present for that to be possible.

Answer:

$F {(0.24)}^{2} = 13.6 \times {10}^{ - 8} \\ F = \frac{13.6 \times {10}^{ - 8}}{ {(0.24)}^{2} }N$
