10)A car is moving from rest and attained a velocity of 80 m/s. Calculate the
acceleration of the car after 5 s?
Answer:
initial velocity (u)=0
final velocity (v)=80m/s
time(t)=5s
acceleration (a)=?
Explanation:
we have
v=u+at
80=0+a×5
5a=80
a=80/5=16m/s²
A car is traveling in a race. The car went from the initial velocity of 35 m/s to the final velocity of 65 m/s in 5 seconds. What is the acceleration? 0-13 m/s2 0-6 m/s2 0.6 m/s2 O 13 m/s2
Answer:
6m/s²
Explanation:
Given parameters:
Initial velocity = 35m/s
Final velocity = 65m/s
Time taken = 5s
Unknown:
Acceleration = ?
Solution:
Acceleration is the rate of change of velocity with time taken;
Acceleration = [tex]\frac{Final velocity - Initial velocity }{time}[/tex]
So;
Acceleration = [tex]\frac{65 - 35}{5}[/tex] = 6m/s²

Which object has the most thermal energy?
Answer:
B
Explanation:
The object with the most thermal energy is the choice B. This is because from the given choices, it has the most mass and highest temperature of all the bricks.
Thermal energy is the sum total of the average kinetic energy within the system.
It is mathematically expressed as:
Quantity of energy = mass x specific heat x change in temperature
We see that the quantity of the thermal energy is directly proportional to mass and temperature changes.
Answer:
B. a 4 kg brick at 25 degrees Celsius
Explanation:
did the quiz <3

Abdul works at the planetarium where he is responsible for creating a show on stars. His show is entitled "A Star is Bom," and it will explain the
forces that create a star.
Abdul is creating a timeline of a star's life including its beginning, middle, and end. Abdul found a picture to include of the region around a star
before its formation begins. What does it look like?
Answer:
dust cloud
Explanation:
Stars are formed from the accumulation of the dust as well gases in the solar system. The dust and the gases collapses due to the the gravity forces and the stars are formed.
They are formed within the clouds of the dust and gases and are scattered in the galaxies. The stars are formed in a million of years from the dust clouds.
In the context, Abdul have a picture of a dust cloud which looks smoky and dusty which is the initial stage of the stars formation due to the gravity. It is the region of the star that looks like a cloud of dust before the formation of the star.
In which direction does an applied force move an object?
Question 1 options:
independent of the force
in the opposite direction of the force
in the same direction as the force
perpendicular to the force
Answer:
in the opposite direction of the force
Answer:
The force applied moves the object in the direction of the force. Suppose if the force is applied to the moving object in that case object moves in the direction of the stronger force. Thus, according to the given question the applied force moves the object in its direction.
that means it's the 2nd option( in the opposite direction of the force

I need the answer me too
Answer:
p and q are 4.0 m apart
moments around q
4 p = (10 * 5) + (4 * 2) - (8 * 1)
p = 12.5

Explanation:
When a warm object is heated up, the thermal radiation it emits changes. Give two ways in which the thermal radiation changes
Answer:
*The increase in thermal energy the maximum emission of radiation changes according to Wien's law
*The increase in thermal energy he intensity of the energy increases significantly, proportional to the fourth power of the temperature
Explanation:
When bodies heat up, the vibrations of their molecules and atoms increase, due to the energy, therefore the internal energy (Temperature) of the body also increases.
The increase in thermal energy relaxes in an increase in body temperature, when this happens the maximum emission of radiation changes according to Wien's law that gives a shift towards the visible as the temperature increases.
Furthermore, the intensity of the energy increases significantly, in a curve described by the Planck expression.
These increases are proportional to the fourth power of the temperature

Explanation:
The model above shows sunlight that is directly hitting one side of the earth during its winter season. Which sentence explains why this area is experiencing shorter hours of daylight
Answer:
During winter time the northern hemisphere leans away from the sun due to the rotation of earth and due to this change the sunlight is not direct on these areas instead it is spread and due to this the shadows are longer and the sunlight is not intense. The earths rotation around the sun causes the seasons to change and that is why we experience shorter hours of daytime.

Which type of energy transfer is responsible for the movement of magma in Earth's interior? A)conduction B)convection C)radiation D)melting
Answer:
B. Convection.
Explanation:
Convection is an energy transfer process which typically involves the transfer of heat as a result of the movement of mass. Convection is generally considered to be a more effective and efficient means of heat transport in the Earth when compared to conduction. The movement of tectonic plates is caused by the convection current because the heat gains pressure underneath the crust.
Hence, the type of energy transfer which is responsible for the movement of magma in Earth's interior is convection.
Additionally, subduction zone is a zone which represents the collision between the two (2) tectonic plates of planet earth. Subduction zone occurs in countries such as Japan, Canada, Indonesia, Russia, Alaska, and around the Pacific Ocean.
Generally, subduction zones are responsible for high intensity earthquakes, volcanoes and tsunamis around the world.

The time taken for the iPod to fall from the top table is 0.5 s.
The given parameters;
height of the table, h = 1.2The time taken for the iPod to fall from the top table is calculated as follows;
[tex]h = v_0t + \frac{1}{2} gt^2\\\\h = 0 + \frac{1}{2} gt^2\\\\h = \frac{1}{2} gt^2\\\\gt^2 = 2h\\\\t^2 = \frac{2h}{g} \\\\t = \sqrt{ \frac{2h}{g} } \\\\t = \sqrt{ \frac{2\times 1.2 }{9.8} }\\\\t = 0.5 \ s[/tex]
Thus, the time taken for the iPod to fall from the top table is 0.5 s.
