Natalie lifts a 15-kg rock from the ground onto a 1.5 meter high wall. what is the amount of potential energy she has given the
Zina [86]
The amount of gravitational potential energy acquired by the rock is equal to:
\Delta U = mg \Delta h
where 
m is the mass of the rock
g is the gravitational acceleration
\Delta h is the increase in height of the rock

Substituting the data of the problem, we find
\Delta U=(15 kg)(9.81 m/s^2)(1.5 m)=220.7 J
So, Natalie gave 220.7 J of energy to the rock.

50POINTS PLEASE HELP SPACE QUESTION
leonid [27]
Regardless of the time of year, the northern and southern hemispheres always experience opposite seasons. This is because during summer or winter, one part of the planet is more directly exposed to the rays of the Sun than the other, and this exposure alternates as the Earth revolves in its orbit.

A grating with 250 grooves mm is used with an incandescent light source. Assume the visible spectrum to range in wavelength from
NeTakaya

The number of orders that one can see the entire visible speed is 5 orders.

<h3>How to calculate the orders?</h3>

From the information given, it should be noted that the grating spacing will be:

d = (1.00 × 10^-4) / 250

d = 4000nm

Therefore, the number of times that are needed to complete the order will be the same as the number of orders which the long wavelength time will be visible. This will be:

= (4000 × sin 90°)/700

= 5.71

Therefore, the maximum orders will be 5.

A 30.0 kg child, initially at rest, slides down a 2.0 m tall slide. The child reaches the bottom of the slide with a speed of 6
HACTEHA [7]

Answer:

Explanation:

Total energy is constant

E = mgh + ½mv² + Fd

At the top of the slide, all energy is potential

E = mgh + 0 + 0

At the bottom of the slide, all potential energy has converted to kinetic and work of friction.

mgh = ½mv² + W

W = mgh - ½mv²

W = 30.0[(9.81)(2.0) - ½6²]

W = 48.6 J

student conducted an experiment and find the density of an ICEBERGE. A students than recorded the following readings. Mass 425
Fiesta28 [93]

Complete Question

The complete question is shown on the first uploaded image

Answer:

The experimental value of density is   \rho  =  1.05*10^{3} \ kg/m^3  \pm  101 \ kg/m^3

Comparing it with the value of density of water (1.0*10^{3} \ kg/m^3) we can see that the density of ice is greater

Explanation:

From the question we are told

    The mass is M  =  (425 \pm 25) \ g =(0.425  \pm 0.025) \ kg

   The volume is V  =  (405 \pm 15 ) \ mL = (0.000405 \pm 1.5*10^{-5}) \  m^3

The experimental value of density is mathematically evaluated as

        \rho =  \frac{M}{V}

       \rho =  \frac{0.425}{0.000405}

       \rho =  1.05 *10^{3} \ kg/m^3

The possible error in this experimental value of density is mathematically evaluated as

        \frac{\Delta \rho}{\rho} =  \frac{\Delta  M}{M} +\frac{\Delta  V}{V}

substituting value

         \frac{\Delta \rho}{1.05*10^{3}} =  \frac{0.025}{0.425} +\frac{1.5*10^{-5}}{0.000405}

        \Delta \rho  = 101 \ kgm^{-3}

Thus the experimental value of density is

             \rho  =  1.05*10^{3} \ kg/m^3  \pm  101 \ kg/m^3
