Answer:
circular motion
Explanation:
Circular motion can be regarded as
movement of particular object along the circumference in a circle. It is
rotation of particular object along a circular path. Circular motion could be
uniform, along with constant angular rate of rotation as well as constant speed. It could also be non-uniform along with changing rate of rotation. The acceleration that is been experienced when one is in uniform circular motion is called"Centripetal acceleration"
Convection currents is type of current that takes place after a reservoir of fluid has been heated at the bottom, then cool at the top.the fluid expand as a result of Heat , then density decreases, the plates on top of them is been carried as a result of circular motion of the convection
A convention current is a circular movement which is set up due to temperature difference between two layers of a fluid.
What is a convection current?A convention current is a movement which is set up due to temperature difference between two fluids.
Convection currents are set up in liquids and gases.
Hotter and less dense fluids move upwards while colder and denser fluids move downwards.
Therefore, convection currents involve circular motion.

Answer:
A roller coaster:
The first law states that an object either remains at rest or continues to move at a constant velocity, unless it is acted upon by an external force.
Hope this helps!
Answer:
This
Explanation:
First Law: Newtons first law of motion explains what happens in a car crash because it basically states that the passenger will continue to travel at the same velocity until an unbalanced force acts on he or she. The force that will act upon he or she would be the window, so you should always wear a seat belt!
Second Law: In other words, it states that the force that is applied in the crash is proportional to mass of impacting cars. This means that the bigger the force of impacting cars, the bigger the force applied, which implies a greater destruction.
Third law: Newton's Laws Applied to Collisions. Newton's third law of motion is naturally applied to collisions between two objects. In a collision between two objects, both objects experience forces that are equal in magnitude and opposite in direction.

When you look into your bathroom mirror, are you upside down
(inverted) or right side up (upright)?
Is this a real or virtual image?
Why?
What is the focal length of a bathroom (flat) mirror?
Answer:
When the image distance is positive, the image is on the same side of the mirror as the object, and it is real and inverted. When the image distance is negative, the image is behind the mirror, so the image is virtual and upright.
Explanation:
A 95 kg falling trunk strikes the ground with a speed of 40 m/s. Assuming that there is no loss of energy due to air resistance, what is the height from which the trunk falls?
Answer:
80 m or 81.3 m
Explanation:
Initially it had no velocity(as at rest). Let the height be h
Using conservation of energy:
Initial KE + PE = final KE + PE
(1/2) m(0)² + mgh = (1/2) m(40)² + mg(0)
mgh = (1/2) m (1600)
2gh = 16000
h = 1600/(2*10) {for g = 10}
h = 80
80 For g = 9.8, h = 81.3 m
Using Newton's eqⁿ of motion:
v² = u² + 2aS
40² = 0² + 2(g)S
1600/2g = S
For g = 10, S = 80 m
g = 9.8, S = 81.33 m

Evaluating each group of values for which is correctly arranged from greatest to least.
(-3, -1, 0, 2, 7) : - 1 is greater than - 3 (the group isn't arranged from greatest to least)
(9, 7, 6, -5, -4) : - 4 is greater than - 5 ; hence, the group isn't arranged from greatest to least
(8, -6, 5, -4, 1) : 5 is greater than - 6 ; hence, the group isn't arranged from greatest to least
(-3, -4, -7, -8, -9) ; the group of numbers here is arranged from greatest to least ;

Consider two spinning tops with different radii. Both have the same linear instantaneous velocities at their edges. Which top has a smaller angular velocity? the top with the smaller radius because the radius of curvature is inversely proportional to the angular velocity the top with the smaller radius because the radius of curvature is directly proportional to the angular velocity the top with the larger radius because the radius of curvature is inversely proportional to the angular velocity The top with the larger radius because the radius of curvature is directly proportional to the angular velocity
Answer:
the top with the largest radius because the radius of curvature is inversely proportional to the angular velocity
Explanation:
Angular and linear velocity are related
v = w r
w = v / r
Therefore, if the linear velocity of the two is the same, the one with the smaller radius has the higher angular velocity.
When reviewing the answers, the correct one is:
the top with the largest radius because the radius of curvature is inversely proportional to the angular velocity
The top that has a smaller angular velocity is D. the top with the larger radius because the radius of curvature is directly proportional to the angular velocity.
It should be noted that the top that has a higher angular velocity will be the top with the smaller radius because the radius of curvature is inversely proportional to the angular velocity
On the other hand, since the two spinning tops have different radii while both have the same linear instantaneous velocities at their edges, then the top that has a smaller angular velocity is the top with the larger radius because the radius of curvature is directly proportional to the angular velocity.

A 5kg particle moving at a speed of 10m/s to the right makes an elastic collision with a wall and rebounds backward calculate the magnitude of the impulse of the body
Answer:
The magnitude of the impulse experienced by the particle is 100 kg.m/s.
Explanation:
Given;
mass of the particle, m = 5 kg
initial velocity of the particle, v₁ = 10 m/s
assuming the particle rebounds with same velocity backwards, v₂ = - 10 m/s
The impulse experienced by the particle is the change in linear momentum;
J = ΔP = mv₁ - mv₂
J = m(v₁ - v₂)
J = 5 (10 - (-10))
J = 5 (10 + 10)
J = 5(20)
J = 100 kg.m/s
Therefore, the magnitude of the impulse experienced by the particle is 100 kg.m/s.
AM and FM stand for two different processes that are used to code voices and music for transmission. What does AM stand for? 1. Amplitude Modulation 2. Amplitude Mediation A
Answer:
1. Amplitude Modulation
Explanation:
AM is an acronym for Amplitude Modulation and it's refers to a process that is typically used for coding sounds such as voices and music for transmission from one point to another.
On the other hand, FM is an acronym for frequency modulation used for the propagation and transmission of sound waves.
Basically, the two forms of modulation are used for broadcasting in radio transmission.
Electromagnetic waves is a propagating medium used in all communications device to transmit data (messages) from the device of the sender to the device of the receiver.
Generally, the most commonly used electromagnetic wave technology in telecommunications is radio waves.
Radio waves can be defined as an electromagnetic wave that has its frequency ranging from 30 GHz to 300 GHz and its wavelength between 1mm and 3000m. Therefore, radio waves are a series of repetitive valleys and peaks that are typically characterized of having the longest wavelength in the electromagnetic spectrum.
