Answer:
15.8640053791 s
392.780107582 m
29.5184032275 m/s
Explanation:
0 denotes initial
x denotes displacement
c denotes car
t denotes truck
r denotes rear
For the car
The displacement of the truck will be
From the above two equations we get
The time taken is 15.8640053791 s
The distance the car travels is 392.780107582 m
The velocity of the car is 29.5184032275 m/s
Answer:
reflection is the act of reflecting or the state of being reflected while echo is
reflection of sound waves from a surface back to the initial listener
By heat touching heat I think that’s right
Answer:
D
Explanation:
The negative feedback is responsible for maintaining equilibrium (stability) in a system as it lessens effects, which is contrary to positive feedback which increases reaction and moves a system further away from equilibrium (stability), It does so by amplifying the effects of a product or event and occurs when something needs to happen quickly. e.g
- Insulin lowers down blood sugar levels, so when the body detects that it has too much sugar, the pancreas is prompted to release insulin and only stops when balance is achieved; hence, negative feedback.
- When there is a tear on the skin, a chemical is released. This chemical causes platelets in the blood to activate, hence they release a chemical which signals more platelets to activate, until the wound is clotted, positive feedback.
They exhibit identical behaviors with regard to changes of phase.
If there is any difference, it is too small to be measured, and none
has been observed.
