Explanation:
The rock cycle works by the rocks moving around. Weathering and erosin makes sediment or something like sand, that sand is put under a lot of pressure until it becomes a solid mass. After that heat and more pressure are added to the rock to make it metamorphic. after that it is heated again until it becomes magma. the ignious rock is made by the cooling of the lava( its lava when it gose above ground). Then the whole cycle repeats.

a 0.15 kg baseball has a momentum of 0.78 kg*m/s just before it lands on the ground. What was the ball's speed just before landing?
Answers
Explanation:
An impulse describes a change in momentum. The change in momentum of an object is its mass times the change in its velocity.
The change in moment is given by the expression below
Δp=m⋅(Δv)=m⋅(vf−vi) .
Given data
mass m= 0.140-kg
initial velocity vi= 120 m/s
final velocity vf= 1 m/s
substituting we have
Δp=m⋅(Δv)=0.14⋅(1−1.2)
Δp=m⋅(Δv)=0.14⋅(-0.2)
Δp= 0.028 kg m/s
The change in momentum was found to be Δp= 0.028 kg m/s
The speed of the ball (i.e the velocity since it has a direction in a specified time) is 5.2 m/s before it landed.
From the given information,
the mass of the baseball = 0.15 kgthe momentum of the baseball = 0.78 kg m/sFor an object moving in a direction in a specified time, the momentum of the object is usually directly proportional to the mass and velocity.
∴
Momentum = mass × velocity
velocity = momentum/mass
velocity = 0.78 kgm/s ÷ 0.15 kg
velocity = 5.2 m/s

What is the difference between serous and mucous membranes?Serous membranes usually line closed cavities within the body, for example, the pericardial cavity. These membranes secrete a serous or watery fluid.
On the other hand, mucous membranes are thicker, and the line surfaces of the body are exposed to the external environment, for example, the respiratory tract. These membranes secret mucus but sometimes they can secret liquids, an example is the conjunctiva.

A cyclist turns a corner with a radius of 50m at a speed of 10m/s. The cyclist's acceleration is 2 m/s².
What is acceleration?The rate at which an item changes its velocity is known as acceleration, a vector quantity. If an object's velocity is changing, it is acceleration. The net acceleration that objects get as a result of the combined action of gravity and centrifugal force is known as the Earth's gravity, or g. It is a vector quantity whose strength or magnitude is determined by the norm and whose direction correlates with a plumb bob.
a = v²/r
a = (10m/s)² / 50m

An astronaut floating in space throws a wrench forward with the force of 10 N.
How much force does the wrench apply to the astronaut?
A. greater than 10 N
B. less than 10 N
C. zero; the wrench does not apply a force
D. exactly 10 N
Answers
The wrench applies greater than 10 N force to the astronaut. The correct option is A.
What is Newton's third law of motion?Newton's third law of motion, which states that for every action, there is an equal and opposite reaction.
When the astronaut throws the wrench forward with a force of 10 N, the wrench will apply an equal and opposite force of 10 N to the astronaut in the opposite direction.
Here other options are,
Option B. Less than 10 N is not true because the force applied by the wrench to the astronaut is equal and opposite to the force applied by the astronaut to the wrench, which is 10 N.
Option C. zero; the wrench does not apply a force is not true because the wrench is exerting a force on the astronaut in the opposite direction to the direction in which the wrench is thrown.
Option D. exactly 10 N is not true because the force applied by the wrench to the astronaut is equal and opposite to the force applied by the astronaut to the wrench, which is 10 N, and the two forces act in opposite directions.
Therefore, the force applied by the wrench to the astronaut is greater than 10 N.
