If an object is moving and it changes its position by 2 min
every 4 s starting from the origin, then the position vs. time
graph is:
Answer: a straight line with a positive slope
Explanation:
If an object is moving and it changes its position by 2 units every 4 s starting from the origin,
What is speed?The total distance covered by any object per unit of time is known as speed. It depends only on the magnitude of the moving object. The unit of speed is meter/second.
Learn more about speed from here If an object is moving and it changes its position by 2 units every 4 s starting from the origin,
speed = distance /time
= 2 units / 4 seconds
= 0.5 units/seconds
Thus, the speed of the object would be 0.5 units /seconds

A seesaw pivots as shown in below. What is the net torque about the pivot point?
With explanation please
I GIVE 25 POINTS
Answer:
2.3 Nm clockwise
Explanation:
Take counterclockwise to be positive and clockwise to be negative.
∑τ = (3 N) (2.5 m) − (7 N) (1.4 m)
∑τ = 7.5 Nm − 9.8 Nm
∑τ = -2.3 Nm
The net torque is 2.3 Nm clockwise.
What is the average of 255, 242, 245?
Answer:
The average is 247.33 if it is for the whole number then it is 247
Explanation:
I did it by adding it all together and dividing it by 3
Answer:
247.33 is the average.
Explanation:
To find the average of a set of numbers:
a. add them up.
b. divide by how many numbers there are.
SO:
a. 255 + 242 + 245 = 742.
b. 742 (total) divided by 3 (# of numbers) = 742/3 = 247.33.

A bicycle is going 2.6 m/s when it speeds up to 15.4 m/s in 8 seconds. What is the acceleration?
Answer:
acceleration is 1.6 m/s^2
Explanation:
This is a question involving Kinematics so we can use one of the kinematic equations.
Given info: Vi= 2.6 m/s. Vf= 15.4 m/s. T= 8s
We need to solve for acceleration
The best equation to use is (Vf = Vi + at) as it contains all the info we need to solve for acceleration.
Now substitute the values given into the equation.
Vf = Vi + at >> 15.4 = 2.6 + a8
Now solve for a by rearranging the equation.
15.4 -2.6= 8a >> 12.8=8a >> 12.8/8= 8a/8 >> 1.6 =a
NOTES:
Acceleration is the rate of increase of velocity
Vf is final velocity or velocity after acceleration/de-accaeleration occurs
Vi is intial velocity or velocity before acceleration or de-accaeleration occurs
Time is time it took for a certain motion to occur.
see attached photo below!
Answer:
0 m/s²
Explanation:
Velocity is the slope of the position vs time graph. The graph is linear, so the velocity is constant. Since the velocity is constant, the acceleration is 0.

Please help me fast and i brainliest!! Two balls are released from the same height. Ball A is released on the surface of Earth, and ball B is released on the surface of the moon. The mass and net force on each ball are recorded in the table. Net Force (N) Mass (kg) Ball A 19.6 2 Ball B 9.6 6 Ball C 6.6 ? Which statement is correct about the mass of ball C, which is released on the surface of the moon from the same height? The mass of ball C is less than the masses of ball A and ball B. The mass of ball C cannot be determined from the information provided. The mass of ball C is greater than the masses of ball A and ball B. The mass of ball C is greater than the mass of ball A but less than the mass of ball B
Answer:
If they both start at the same height then most likely that means that each has an intical velocity and a net force sooooo ball A 19.6
Explanation:
Answer: The mass of ball C is greater than the mass of ball A but less than the mass of ball B.

Complete this sentence. If volume remains the same while the mass of a substance ________, the density of the substance will_______________. increases, stay the same decreases, stay the same decreases, increase increases, increase
The answer is increase.
d = m/v. if you increase the mass without changing the volume, the density will increase.
define the focus of a concave lens
Answer:
Principal focus of concave lens -
★ The point at which rays parallel to principal axis coming from infinity appear to converge after being refracted from concave lens is called the principal focus of concave lens.
________________________
• Additional information -
★ Principal focus - A number of rays parallel to the principal axis after reflection from a concave mirror meet at a point on the principal axis or appear to come from a point after reflection from a convex mirror on the principal axis. This is called principal focus.

What are significant figures?In positional notation, significant figures refer to the digits in a number that is trustworthy and required to denote the amount of something, also known as the significant digits, precision, or resolution.
If a number describing the result of a measurement (such as length, pressure, volume, or mass) includes more digits than the number of digits permitted by the measurement resolution, only the digits allowed by the measurement resolution can be significant figures.
As given in the problem we have to convert 3 x 10⁻⁹ s into milliseconds
1 second = 1×10³ milliseconds
3 x 10⁻⁹ seconds = (3 x 10⁻⁹) × (1×10³ )
= 3 x 10⁻⁶milliseconds
Thus, 3 x 10⁻⁹ s converted into milliseconds it would be 3 x 10⁻⁶ milliseconds

Throwing a rock vertically in using Kinetic Energy, it then transforms into Gravitational Energy as the rock falls.
Explanation:
First, as Kwane rubbing his and and iron his clothes using the energy to create heat, that is thermal being transformed.
The rock being thrown uses kinetic energy and due to graviational force of the earth, it is being transformed into Potential Gravitational Energy.
>Explain whether life could exist on other
planets or moons in our solar system.
Answer:
The direct answer to the question "Can there be life..." is that there is potentially a non-zero possibility. Testing the null hypothesis, that there "cannot be life" is quite difficult. Evidence for and against both positions exists. However strong the arguments for life, space provides many harsh environments, yet we know deep in our oceans at hydro-thermal vents or in volcanic geysers there is life. Seeing volcanism on other worlds at least provides a necessary energy source. But the null hypothesis has a fatal flaw. We know of one location where there is life, and we discover over and over again that its conditions are not very special in the Universe. The famous Drake equation goes much further, to single out intelligent life that still exists today and wishes to communicate. But in very sad news for the null hypothesis, even it is non-zero.

Describe all of the forces acting on the ice cream in the root beer float. Relate these forces to the fact that the ice cream is floating
Answer: Sample Response: The root beer exerts a force on all sides of the ice cream. These forces are all equal and cancel each other out. Gravity pushes downward on the ice cream. This can also be called the weight of the ice cream. Buoyant force pushes the ice cream upward. The ice cream floats because the buoyant force is greater than the weight of the ice cream.

How long would it take Jesse with an acceleration of -2.50 m/s^2 to bring his bicycle with an initial velocity of 13.5 m/s to a complete stop?
a.6.1 s
b.3.7 s
c.12.1 s
D.5.4 s
Answer:
use first equation of motion v=u+at..v is 0..since we have to take him to rest and u is 13.5
Explanation:
u = 13.5 m/s
a = - 2.5 m/s^2
v = u + at
0 = 13.5 - 2.5 * t
t (time to reach a complete halt) = 5.4 sec

A satellite in space has a mass of 252 kg. The engines on it provide a net force of 6.81×10-3 N. How long will it take for this satellite to go from rest to a final velocity of 262 m/s forward?
Acceleration = (force) / (mass)
Acceleration = (6.81 x 10⁻³ N) / (252 kg)
Acceleration = 2.70 x 10⁻⁵ m/s²
Time = (change in v) / (acceleration)
Time = (262 m/s) / (2.70 x 10⁻⁵ m/s²)
Time = 9,703,704 seconds
That's 2,695.5 hours , or 112.3 mean solar Earth days .
