Answer:

The Law of the Conservation of Energy

Explanation:

The Energy Conservation Act tells us that any form of energy changes from one form to another. And that you can never have a higher amount of energy than you originally got. That is, if you have 100 [J] of energy to be transferred as heat from one medium to another, only 100 [J] can be used to be transferred, no amount greater than this value can be transferred.

The particular study of Energy Transfer in the form of heat is important in sciences such as thermodynamics and heat transfer.

erastova [34]

Answer:

(a). The ball's centripetal acceleration is 16.17\times10^{2}\ m/s^2

(b). The magnitude of the net force is 232.9 N.

Explanation:

Given that,

Mass of baseball = 144 g

Speed = 81 mph = 36.2 m/s

Distance = 81 cm

(a). We need top calculate the ball's centripetal acceleration just before it is released

Using formula of centripetal acceleration

a=\dfrac{v^2}{r}

Where, v = speed

r  = radius

Put the value into the formula

a=\dfrac{(36.2)^2}{81\times10^{-2}}

a=1617.82\ m/s^2

a=16.17\times10^{2}\ m/s^2

(b). We need to calculate the magnitude of the net force that is acting on the ball just before it is released

Using formula of force

F=\dfrac{mv^2}{r}

Put the value into the formula

F=\dfrac{144\times10^{-3}\times(36.2)^2}{81\times10^{-2}}

F=232.9\ N

Hence, (a). The ball's centripetal acceleration is 16.17\times10^{2}\ m/s^2

(b). The magnitude of the net force is 232.9 N.

What is the magnitude of a point charge in coulombs whose electric field 58 cm away has the magnitude 2.8 N/C?
Yuliya22 [10]

Answer:

q = 1.05 × 10^-10 C

Explanation:

E = 2.8 N/C

r = 58cm = 0.58m

k = 9×10^9

q = ?

E = f/q

E = kq/r²

q = E*r²/k

q = (2.8×0.58²)÷9×10^9

q = 1.05 × 10^-10 C

1. What is the difference between a patent, latent, and plastic shoe<br> Impression?
Irina-Kira [14]

Answer:

Patent fingerprints can be made by blood, grease, ink, or dirt. This type of fingerprint is easily visible to the human eye. Plastic fingerprints are three-dimensional impressions and can be made by pressing your fingers in fresh paint, wax, soap, or tar.

I Hope this helps!

Sincerely; Victoria<3

mr_godi [17]
Impulse is change in momentum.  The initial momentum was
0.1kg*11m/s=1.1kg m/s.
The second momentum is 0.1*(-8.8m/s)=-0.88 (since it's moving backward now)
The difference is P1-P2 = 1.1-(-0.88)=1.98kg m/s
