so by the shape look at this what will the time acceleration speed or velocity be in a beyblade what is the average if the beyblade spins for atleast 45 seconds and the beyblade weighs 55 grams what is the speed or acceleration of the beyblade?
Answer:
the answer is 1.09 speed
Answer:
2.00
Explanation:
pls help, i really dw fail :(
Answer:
Using the Newton equation
V²=U² +2as
Given; V=9.2m/s U = 0m/s( because it starts from rest)
S=26.2m.
9.2²=0²+2(26.2)a
a =9.2²/2(26.2)
a=84.6/52.4
a=1.60m/s²
Answer:
2.A
3.D
Explanation:
HOPE THIS HELPS!! :)

What is the total energy of a system with KE = 1368 J and a PE = 5782J? Express your answer in kJ.
Answer:
7.150 KJ
Explanation:
The total energy of a system is the sum of the potential and kinetic energy in the system. According to this question, the kinetic energy (KE) = 1368 J and a potential energy (PE) = 5782J.
Total energy of the system will be PE + KE as follows;
1368J + 5782J
= 7150J
However, the question demanded that the answer be in kJ (kilojoules), which is higher than the joules.
Since 1kJ = 1000J
7150J = 7150/1000
= 7.150kJ
32. Increasing the amplitude of a sound wave produces a
sound with
1. lower speed
2. higher pitch
3: shorter wavelength
4. greater loudness
Answer:
4
Explanation:
because amplitude of a sound wave is related to loudness of the sound, so the higher the amplitude, the louder the sound

What force is necessary to give a 1000 kg rocket an acceleration of 150
m/s2?
Answer:
150,000N
Explanation:
Force=Mass*Acceleration
F=ma
Mass of the rocket=1000Kg
Acceleration=150 m/s²
Force=1000*150=150,000kgm/s²=150,000N

You and your 3 friends are driving down the road. All the wheels go flat at the exact same time, that's not good. You have to use a 2,100 N force to push the car 4 meters to the side of the road. How much work did you do on the car?
Answer:
Workdone = 8400 Nm
Explanation:
Given the following data;
Force = 2100 N
Distance = 4 meters
To find the work done;
Workdone = force * distance
Workdone = 2100 * 4
Workdone = 8400 Nm
Therefore, the amount of work done on the car is 8400 Newton meters.
8. Where does ½ to ⅓ of the ocean pollution come from?
Answer:
The majority of pollutants that make their way into the ocean come from human activities along the coastlines and far inland. One of the biggest sources of pollution is nonpoint source pollution, which occurs as a result of runoff.

As Clinton walks he pushes his shoe against the track.
Which of the following best describes the reaction force to Clinton's shoe pushing against the track?
OA. The track pushes back on Clinton's shoe with the same force.
ОВ.
The track pushes in the same direction as Clinton's shoe with the same force.
OC. The track pushes against gravity with the same force.
The track pushes in a different direction with a different force.
Answer:A:The track pushes back on Clinton's shoe with the same force.
Explanation:According to Newton's third law of motion, for every action force there is an equal and opposite reaction force. In this case, the action force is Clinton's shoe pushing on the track. As this happens, there is an equal and opposite reaction force in which the track pushes back on Clinton's shoe with the same force.

Which type of earthquake waves are responsible for most of the damage caused by an earthquake? Why?
please helppppp its due tomorrow
Answer:
Surface waves travel along the surface. There are two types of body waves: P-waves travel fastest and through solids, liquids, and gases; S-waves only travel through solids. Surface waves are the slowest, but they do the most damage in an earthquake.
Answer:
surface waves
Explanation:
they have the strongest vibration and can cause the most damage
A 3500 N is force is applied to a spring that has a spring of constant of k= 14000 N/m. How far from equilibrium will the spring be displaced?
Answer:
the spring be displaced by 25.0 cm
Explanation:
The computation is shown below:
As we know that
F= -K × x
So,
[tex]x = \frac{-F}{K}[/tex]
Now
[tex]x = \frac{-3500}{14000} \\\\[/tex]
= -0.250m
= 25.0 cm
Hence, the spring be displaced by 25.0 cm
