The uniform movement allows finding the results for the helicopter displacement during the 10 s is: 700 m
Kinematics studies the motion of bodies, finding relationships between the position, velocity and acceleration of the body, in the special case that the acceleration is zero, it is called uniform motion and is described by the equation
[tex]v = \frac{\Delta s}{t}[/tex]
Where v is the average velocity, Ds is the displacement and t is the time
Δs = v t
They indicate that the average speed is 70 m / s and the travel time is t=10.0s
Let's calculate
Δs = 70 10.0
Δs = 700 m / s
In conclusion using the uniform movement we can find the results for the helicopter displacement is: 700 m

The magnitude of the helicopter's displacement is 700 meters.
Given the following data:
Velocity = 70 m/sTime = 10 seconds.To find the magnitude of the helicopter's displacement:
Velocity can be defined as the rate of change in displacement (distance) with time.
Also, velocity is a vector quantity and as a result of this, it has both magnitude and direction.
Mathematically, velocity is given by the formula;
[tex]Velocity = \frac{displacement}{time}[/tex]
Making displacement the subject of formula, we have:
[tex]Displacement = velocity[/tex] × [tex]time[/tex]
[tex]Displacement = 70[/tex] × [tex]10[/tex]
Displacement = 700 meters.
Therefore, the magnitude of the helicopter's displacement is 700 meters.

If a male runner in the fourth starting position ran the 400 m race in 44.40 s, how would you
calculate his average speed?
If a male runner in the fourth starting position ran the 400 m race in 44.40 s, then for calculating his average speed we have to divide the total distance covered by the time taken by him to cover the distance.
His average speed would be 9.0 meters/second.
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 a meter/second. The generally considered unit for speed is a meter per second.
The mathematical expression for speed is given by
speed = total distance /Total time
If a male runner in the fourth starting position completed the 400 m race in 44.40 s, we must divide the total distance traveled by the amount of time it took him to complete the course to get his average pace.
the average speed of the runner = 400 meters/44.40 seconds
= 9.0 meters/second
Thus, his average speed.be his average speed would be 9.0 meters per second

Answer:
D
Explanation:
I had the question on an exam, I answered D and I got 97% on the test, I got it correct with the answer of D. TO be fair I guessed on the test and got it right, lucky guess I suppose.
Answer:
According to electrostatic concept the electric potential will be toward the negative charge and the coulomb force will be directed towards the negative charge.
Due to that 4 is the correct option.

Review what you have done for that unit. Skim over it if you dont have enough time because it would greatly help. If you have mathamatics involved learn or make sure you are perfect at doing the equations you need to do. Just dont cheat because if you get caught you are going to get an imediete F which will be worse then getting half of them wrong. Good luck

How far has a ball traveled after 3.6 seconds when thrown downward at a
velocity 3.75 m/s?
ball traveled 13.5 m/s after 3.6 seconds
Explanation:
u=3.75m/s, t=3.6s, g=9.8m/s².
Therefore, according to the formula,
S=ut+½gt².
S=(3.75×3.6)+½×9.8×(3.6)²
S= 13.5+63.504
S= 77.004m (approximately 77 m)
therefore the distance traveled by the ball is 77m.

Explanation:
Electromagnetic Equipment
An electromagnet is a type of magnet with a magnetic field produced by an electric current. Electromagnets are often used in electrical devices that induce heat for cooking such as an oven (OPTION A).
Capacitor
As the voltage increases, the current decreases (OPTION D).
As the capacitor charges up, the potential difference across its plates begins to increase, and by extension circuit current decreases.
Which of the following is not part of the forces that work together to move the tectonic plates?
-mantle convection
-ridge push
-slab pull
-friction

Mass of the ball: m = 0.50 kg.
Initial speed of the ball: v = 6.0 m/s.
A) its kinetic energy at initial = 1/2mv² = 1/2 × 0.50 × 6.0² Joule = 9.0 Joule.
B) As total energy is conserved., when the ball reaches its maximum height its initial kinetic energy fully transforms into potential energy. Its maximum gain of potential energy is its kinetic energy, that is, 9.0 Joule.
C) Its maximum gain in height be = √(v²/2g) = √(6.0²/2×9.8) m = 1.91 m.

Are your answers to questions 1 and 2 the same? Why or why not? What causes that to be the same or different?
I give Brainliest!
Answer: see below
Explanation:
1) An object at rest stays at rest and an object in motion stays in motion with the same speed and in the same direction unless acted upon by an unbalanced force.
Friction opposes relative motion. In its absence, a moving object will not stop.
2) If you stop pushing, the force of kinetic friction will produce an acceleration in the opposite direction of the velocity, and the object will slow down and stop.
3) No they are not the same, as one has friction and the other has no friction.
