The answer would be A -- Granite.
The actual diameter of the heart is 12.25 cm. Given : Heart measure = 14.7 cm Magnification factor = 1.2
14.7 / 1.2 = 12.25
Answer:
the acceleration is 2.5 MPH over 12 mins.
Explanation:
30 MPH in 12 minutes=
30/12=
2.5
The final object will move with a speed of 1.9 x 10⁻² m/s.
According to the law of conservation of momentum, when two objects meet in a closed system, the sum of their momentums before and after the collision is constant.
Here,
Initial velocity of the bullet, u = 100 m/s
Mass of the bullet, m = 15 g = 0.015 kg
Mass of the object, M = 75 kg
Total momentum before collision, P₁ = mu + (M x 0)
P₁ = 0.015 x 100
P₁ = 1.5 Kgm/s
Total momentum after collision, P₂ = (m + M)v
P₂ = (0.015 + 75)v
P₂ = 75.015 v
According to law of conservation of momentum,
P₁ = P₂
1.5 = 75.015 v
Therefore, the speed with which the final object moves,
v = 1.5/75.015
v = 1.9 x 10⁻² m/s
Hence,
The final object will move with a speed of 1.9 x 10⁻² m/s.

b. just above Earth's surface
c. on Earth's surface
The acceleration of gravity at the surface of the Earth is approximately 9.8 meters (32 feet) per second per second. As a result, during free fall, an object's speed rises by around 9.8 meters per second.
The force that binds all masses in the universe together, particularly the pull of the earth's mass on objects that are close to its surface.
The term gravitational force refers to the force that the earth exerts on a body. Examples of motion caused by gravitational force include the downward motion of water in a river, the downward motion of water in a stream, and the upward motion of a ball when it is thrown.
All physical things with mass are drawn to the gravitational force, which can be thought of as an attracting force. It is the known natural force that is by far the weakest. representation in mathematics. The formula for gravitational force is F = G m 1 m 2 r in mathematics.
The answer is on earth surface
