A car moving round a circular racing track takes 120s to do a lap of 8km what is the speed in km/hr.
Answer:
Solution in photo
Explanation:
A car moves around in a circular racing track, and it takes 120 seconds to do a lap of 8 km, so the speed in km/hr is 239.76 km/hr.
What is Speed?The speed of an object, commonly known as v in mechanics, is a scalar quantity that corresponds towards the size of the change in that object's position over duration or the size of the change in that object's position per unit of time.
The instantaneous velocity is the absolute maximum of the average speed as the time interval's duration gets closer to zero. The cruising pace of an object in a time interval is calculated by dividing its distance traveled by the time interval's duration. Velocity and speed are different concepts.
The given data according to the question is,
Time, t = 120 s
Distance, d = 8 km
s = 8/120
s =0.0666 km/sec or
s = 0.0666/1s × 3600
s = 239.76 km/hr.
Therefore, the speed is 239.76 km/hr.

A Force that does not change an object velocity
Answer:
I think ur wrong to say force doesn't change an object velocity
Explanation:
Force affects how objects move. They change the direction of motion of an object that is already moving. Since force causes a change in the speed or direction of an object, we may say that force causes changes in an object velocity.

Which statement about the relationship between air pressure and air density is accurate?
A) Air pressure decreases as air density increases
B) Air pressure increases as air density increases
C) Air pressure increases as air density decreases
D) Air pressure is unrelated to air density
Answer:
A: Air pressure decreases as air density increases
Explanation:
Pressure is a force exerted on or against an object by being in contact with a substance. Thus, air pressure is due to the bombardment of the air (gas) particles with a surface. Density is defined as the mass per volume of a substance. Thus, air density is defined as the mass of air per unit volume.
If that Explanation does not make any sense let me make it easier.
The air at the top of a mountain is cooler than the air at the bottom. This temperature difference is due to a phenomenon that occurs in Earth’s atmosphere. Air rises and sinks based on differences in temperature and pressure. Here’s a quick experiment that will help explain the role of pressure.Take in a deep breath as if you were ready to blow out birthday candles. Puff your cheeks with air like a chipmunk. Hold it for a few seconds, and then blow the air slowly from your cheeks.Cold air sinks while warm air rises because cold air is denser than warm air. When a lot of cold air sinks, it creates an area of high air pressure where it hits the surface. This high-pressure air flows to an area of low pressure, creating wind. When this air warms, it rises up into the atmosphere.Temperature decreases as altitude increases. That’s why a mountain peak may be covered with snow while the bottom of the mountain is full of green plants and trees. When warm air rises into the atmosphere, it cools. The density of the air increases as it cools, which eventually creates an area of high pressure and starts the cycle again.
If not for this phenomenon of air rising and sinking in the atmosphere, there would be no wind or weather.

In 1630 at the beginning of European settlement, about 425,000,000 hectares of the United States were covered with trees. By 2017, the area covered by trees was reduced to 300,000,000 hectares. What is the percentage decrease in the area covered by trees between 1630 and 2017?
Answer:
29.41%
Explanation:
Given that,
In 1630 at the beginning of European settlement, about 425,000,000 hectares of the United States were covered with trees.
By 2017, the area covered by trees was reduced to 300,000,000 hectares.
We need to find the percentage decrease in the area covered by trees between 1630 and 2017.
The percentage decrease in any value is given by :
[tex]\%=\dfrac{300,000,000 -425,000,000 }{425,000,000 }\times 100\\\\=29.41\%[/tex]
So, the percentage decrease in the area covered by the trees is 29.41%.
Plants appear green because they do not absorb the green wavelengths of light. What happens to those green light waves when they hit a plant? The are diffracted. They are absorbed. They are reflected. They are refracted.
Answer:
They are reflected.
Explanation:
Red light is absorbed while green light is reflected, causing the color to be green in human eyes.
Answer:
C
Explanation:
A ray of light travelling in air enters obliquely into water. Does the light ray bends towards the normal or away from the normal? Why?
Explanation:
The refraction index of water (1.33) is higher than air (1), therefore the light ray will bend towards the normal.

An object completes 10 cycles in 50s.
a. What is the period of its rotation?
b. What is the frequency of its rotation?
Answer:
.
Explanation:
Explanation:
Given parameters:
Number of cycles = 10cycles
Time taken = 50s
Unknown:
Period of its rotation = ?
Frequency of its rotation = ?
Solution:
The period of rotation is the time taken time taken for a body to complete a number of rotation;
Period = [tex]\frac{t}{n}[/tex]
t is the time
n is the number of cycles
Period = [tex]\frac{50}{10}[/tex] = 5s
The period is 5s
Now, frequency is the inverse of period;
F = [tex]\frac{1}{period}[/tex] = [tex]\frac{1}{5}[/tex] = 0.2Hz
If you and your friend are playing tug of war and both are you are pulling with the same amount of force. What will happen?
Answer:
Nothin will move, it will stay the same since no force is greater than the other. it's "the same amount of force" which also means an equal amount of force
Explanation:
The forces are only equal if there is no acceleration (which in the game of tug of war, accelerating yourself and your opponent is the idea). If the force on the rope and the ground are both equal either nothing moves or some other force is being applied in the system.
Hope this helped!
A 1 kg box is sitting on a flat horizontal surface that has a coefficient of static friction value of 0.8. What answer best states the minimum force required to move the box in the horizontal direction?
A. >-9.8N
B. >9.8N
C. >7.84N
D. >9N
The normal force felt by the box has magnitude
F[normal] = (1 kg) g = 9.8 N
so that the maximum magnitude of static friction is

Answer:
3000W
Explanation:
Given parameter:
Weight of safe = 2000N
Height of lift = 6m
Time = 4s
Unknown:
Power used by Rudolph = ?
Solution:
Power is the rate at which work is being done. It is expressed as:
Power = [tex]\frac{Work done }{Time taken}[/tex]
Work done = Weight x height = 2000 x 6 = 12000J
Power = [tex]\frac{12000}{4}[/tex] = 3000W
