If the force on a cart is doubled, what happens to the acceleration of the cart?.
Answer:
It will be doubled
Explanation:
F = ma
Let's consider m = 1 (the mass of the cart is not changing so it is constant),
F = 2, and a = 4.
2 = 1 x 4
When doubling force we need to maintain equality so acceleration should double too. To understand it better find the ratio of force and acceleration 2/4 = 1/2. The ratio of force to acceleration should always equal half in all scenarios, this way we can see how equality is maintained.
2x2 = 1 x (4x2)
4 = 1 x 8, and the ratio of force to acceleration is 4/8 = 1/2.

a rotating wheel requires s to rotate revolutions. its angular velocity at the end of the -s interval is rad/s. what is the constant angular acceleration (in ) of the wheel?
The angular acceleration of the wheel is -20.25 rad/sec^2
Angular acceleration is defined as the rate of change of angular velocity over time.
It is usually expressed in radians per second.It is also known as rotational acceleration.Mathematically, θ = ωo t + 1/2*α*t^2so, α = 2*(θ - ωo t ) / t^2
angular velocity of the wheel = ωo = 96.0 rad/sec
time taken by the wheel to rotate = t = 7 sec
angular distance travelled by the wheel = θ 28 rev
As we know that,
In one revolution the wheel completes 360 degrees which is equals to 6.28319 rad
therefore angular distance traveled = 28 rev * 6.28319 rad
So, the angular acceleration = 2*(28*6.28 - 96*7) / 7^2 = -20.25 rad/sec^2
The question is incomplete, the complete question is 'A rotating wheel requires 7.00 s to rotate 28.0 revolutions. its angular velocity at the end of the 7.00-s interval is 96.0 rad/s. what is the constant angular acceleration (in rad/s) of the wheel?'

a track star runs a 230 m race on a 230 m circular track in 26 s. what is his angular velocity (in rad/s) assuming a constant speed? (enter the magnitude.)
Using the concepts of angular displacement, we got that 0.241 rad/s is the angular velocity of track star which runs a 230 m race on a 230 m circular track in 26 s.
We know very well that angular velocity is given by change in angular displacement per unit time.
Here, we can see that a truck distance covered and length of circular track is same.
Perimeter of circular track is equal to the distance covered by the truck.
It means, truck rounds a full circle in 26 sec
So, the angle covered by truck is 360° or 2π radian.
Initially angle is 0 radian and final angle is 2π radian
Therefore, angular velocity =(θ[tex]_f_i_n_a_l[/tex] -θ[tex]_i_n_i_t_i_a_l[/tex])/time
=> ω=(2π-0)/26
=>w=(2π/26)

=>w=0.241 rad/sec.
Hence, when a track star runs a 230 m race on a 230 m circular track in 26 s, the angular velocity assuming a constant speed is 0.241 rad/sec.

The braking distance does not change. Because both the kinetic energy and the frictional force are doubled.
We found that the stopping distance of a car is proportional to its kinetic energy. Energy is dissipated as heat in the brakes tires and road surface. More energy required means more stopping distance. This explains why the braking distance increases in proportion to the square of the car's speed. The kinetic energy of a car is equal to the braking force multiplied by the stopping distance.
Braking distance also depends on car speed car mass brake and tire wear and road surface. A fast heavy car with worn tires and brakes will have a longer stopping distance on wet or icy roads.

It could be caused by human operations like grading a new road, quake shaking, super volcano, storm waves, or storm-related waves. Mass-wasting is most frequently caused by an increase in water content in the slope. Rapidly dissolving snow or ice, as well as a heavy downpour, can cause the water content to rise.

Distance is a quantitative or qualitative measurement of the distance between two objects or places. Distance can refer to a physical length or an estimation based on other factors in physics or common use (e.g. "two counties over").

you see a manned aircraft in the distance while flying your drone at night. on the left, you're seeing a green light. on the right, you're seeing a red light. which direction is the aircraft headed?
The airplane is heading away from us when we see a manned aircraft in the distance while flying our drone at night.
Distance is the length between two points or items, and it is directionless. Since distance is a scalar attribute, it only takes into account the overall magnitude and ignores the start and end locations. Being a scalar attribute, distance may only be positive or zero; it cannot be the opposite.
Although kilometers (km) and centimeters (cm) or millimeters (mm) can also be used to express shorter distances, the meter (m) is the most used unit of measurement for distance (mm). When calculating distance, the letter D is usually used to denote the distance traveled.

if you run the wire through a strong horseshoe magnet, subjecting 5.00 cm of it to a perpendicular 1.75 t field, what force is exerted on the segment of wire in n?
According to the given statement 17.15 N force is exerted on the segment of wire in n.
How would you define magnitude?Magnitude is essentially "distance or quantity" in the context of physics. In terms of motion, it shows the absolute and relative size, direction, or movement of an object. It is used to describe there is something volume or scope. Quantity in physics typically refers to a size or quantity.
Briefing:The magnitude of the magnetic force on a conducting wire of length I carrying current II, and making an angle θ with a magnetic field of strength B is given by:
[tex]$|\vec{F}|$[/tex] = I l B sin 0
Rearranging to get the current:
I = [tex]$|\vec{F}|$[/tex]/ lB sin0
= 7 * 10⁻³ / 0.75 * (5.5 * 10⁻⁵)sin60
= 195.95 A
[tex]$|\vec{F}|$[/tex] = I l Bsin0
= (195.95)(0.05)(1.75)sin90
=17.15 N
I = 195.95 I
[tex]$|\vec{F}|$[/tex] = 17.15 N

A science class is observing how heat flows from one
object to another by melting ice and boiling water.
Which statements correctly describe how heat flows?
Choose the two statements that apply.
The coolness of the ice is flowing into the warm
water and decreasing its temperature.
The coolness of the water is flowing to the burner
and cooling it.
The warmth from the water is flowing to the ice
and melting it.
The warmth from the burner is flowing to the cold
water and increasing its temperature.
The warmth from the water is flowing to the ice and melting it and The warmth from the burner is flowing to the cold water and increasing its temperature.
What is the flow of heat called?Convection, which is essentially the mass transfer of heat, is the process by which heat is moved from one place to another by the movement of fluids. The transport of heat into the atmosphere involves one of three processes: radiation, conduction, or convection.
What happens during heat flow?Heat flow occurs when a hot object transmits its heat through a conductors to a cooler, similar to how high-energy objects impart their power to low-energy objects. How well a conductor transfers heat will impact how quickly and how much heat is transported.
