A.
rainfall
B.
erosion
C.
snow

A cannon fires a cannonball directly upwards at +150m/s. How long does it take for the cannonball to reach maximum height?
When the mass of the object decreases, explain the effect that change in mass has on the potential and kinetic energy of the object.
When the mass of the object decreases, the potential and kinetic energy of the object also decreases.
WHAT IS KINETIC AND POTENTIAL ENERGY?Kinetic energy is the energy due to the motion of an object while potential energy is the energy due to rest of an object.
The kinetic and potential energy are calculated as follows:
K.E = ½ × mass × velocity ²P.E = mass × acceleration due to gravity × heightTherefore, when the mass of the object decreases, the potential and kinetic energy needed to make it move or be at rest respectively also decreases.

Answer:
it's estimated to within a couple of thousands of years.
Explanation:
For a long time it was thought that the dinosaurs died out 65 million years ago. But Paul explains, 'The dating of those layers of clay around the world is very accurate.
what is represented using a free body diagram
Answer:
a free body diagram (FBD; also called a force diagram) is a graphical illustration used to visualize the applied forces, moments, and resulting reactions on a body in a given condition.
how do animal weather rocks
Answer:
Burrowing animals can cause weathering. By digging for food or making space to live in the animal may break apart rock. The growing roots of a tree can also break apart rock.
) The magnitude of scalar product of two unit vectors perpendicular to each other is
This question involves the concept of the scalar product.
The magnitude of the scalar product will be "0".
SCALAR PRODUCTThe scalar product, also known as the dot product of the two vectors is given by the following formula:
[tex]A.B = |A||B|Cos\theta[/tex]
where,
A.B = Scalar product = ?|A| = Mangnitude of vector A = 1 unit|B| = Magnitude of Vector B = 1 unitθ = Angle between vectors = 90°Therefore,
[tex]A.B = (1)(1)Cos90^o = (1)(1)(0)[/tex]
A.B = 0

Calculate the acceleration of a truck moving along a straight path if its speed increases from
0.0 m/s to 15 m/s in 10.0 s.
Answer:
I'm not to sure but I think the answer is 1.5m/s^2
Explanation:
Acceleration = Change in Velocity over Time.
So we get 15 - 0.0 divided by 10.0 which = 1.5m/s^2
But again I'm no expert I'm learning this stuff just like you guys.
One man lifts a 300 kg crate from the ground to the top of a loading dock 1 meter high. Another man lifts the same crate using a ramp 3 meters long, 1 meter high. What can you say about the amount of work being done?

of 24.3◦
.
The acceleration of gravity is 9.81 m/s
2
.
What is Fn of the incline on the block?
Answer in units of N.
Answer:
W = m g = 2.60 * 9.81 = 25.5 N weight of block
Fn = W cos theta = 25.5 N * cos 24.3 = 23.2 N normal force of plane
