Answer:
0N.
Explanation:
Net force is the sum total of forces acting on an object.
The Fn which is the net force is
450+ (-250) + (-600)+ 600+ 0 + 250 + (-450)
= 450-250+(-600)+ 600+0+250-450
= 0N
The net force is 0

When you stretch a spring, there is energy in the spring's
potential energy store. What word completes the sentence?
Answers
Answer:
field strength i think, I'm not that sure.
ASAP
A spring is stretched downward by a certain length and, as a result, exerts a
force in the upward direction. What happens to the force exerted by the
spring if the length by which it is stretched is reduced by half?
O A. The force exerted by the spring is reduced by half.
B. The force exerted by the spring is doubled.
O C. The force exerted by the spring reduced by one quarter.
O D. The force exerted by the spring remains unchanged.
Answers
Answer:
A
Explanation:
Hooke's law! F(spring)=-kx
There's no tricky square law here. The spring constant doesn't change, only x (distance stretched) changes. Therefore, if distance is halved, Force will be halved.

Shrill sound is of -------------- *
Higher frequency
Lower frequency
Higher amplitude
Lower amplitude
Answers
Answer:
Higher frequency.
Explanation:
Sound are mechanical waves that are highly dependent on matter for their propagation and transmission.
Sound travels faster through solids than it does through either liquids or gases. A student could verify this statement by measuring the time required for sound to travel a set distance through a solid, a liquid, and a gas.
Mathematically, the speed of a sound is given by the formula:
[tex] Speed = wavelength * frequency [/tex]
Generally, the frequency of a sound wave determines the pitch of the sound that would be heard.
A shrill sound refers to a type of sound that is typically sharp, high pitched and as such has higher frequency.
Hence, shrill sound is of higher frequency.

A weight-lifter raises a 2000 N weight through a vertical height of 2.0m in 0.80 s.
What useful power does he develop in doing this?
A
800 W
B
3200W
с
4000 W
D
5000W
Answers
Answer:
D. 5000W
Explanation:
Given the following data;
Force = 2000N
Distance = 2m
Time = 0.8s
To find the power;
First of all, we would determine the workdone by the weightlifter
Workdone = force * distance
Workdone = 2000 * 2
Workdone = 4000N
Now, we can find the power using the formula;
Power = workdone/time
Substituting into the equation, we have
Power = 4000/0.8
Power = 5000 Watts
