F = 245N

The Acceleration of an object in a free fall is 9.8 m/s

force= 25kg X 9.8m/s

D. There is a known constant concentration of C14 in Nature. As we consume living things to survive our bodies (made of carbon) stop replenishing our body's carbon (we stop eating) and start to decay. Since we know the 1/2 life of C14 and the ratio of C14 to normal C12 we can determine fairly accurately how long ago a thing stopped consuming carbon (e.g. when it died)

Alana drew a diagram to compare the life cycles of low-mass and high-mass stars.

Answer:

Explanation:

Both low and high mass stars begin as nebulae, then become protostars. Both use nuclear fusion to form hydrogen in the main sequence.

The differences are that low mass stars have longer life cycles and become white dwarfs. High mass stars have shorter life cycles and undergo supernova explosions.

A golf ball (m = 46.0 g) is struck with a force that makes an angle of 44.4° with the horizontal. the ball lands 193 m away on a

LenKa [72]

Using the formula for bodies in projectile motion, we can calculate for the velocity v:

d = (v^2) * (sin2theta) / g

Substituting the given values:

193 m = (v^2) * (sin(2*44.4)) / (9.8 m/s^2)

v= 50.5 m/s

Calculating for the impulse I,

I = mf * vf – mi * vi
