Do you believe that the universe is expanding?​

Physics
1 answer:
GalinKa [24]4 years ago
6 0

Answer:

Yes

Explanation:

Many scientists believe that the universe is expanding at an increasing rate. Scientists cannot explain how the universe is expanding at an increasing rate because by law of conservation of energy, there is only a finite amount of energy. Thus, scientists have called this new source of energy dark matter and it is all around the universe helping shape and form the universe.

A homing pigeon starts from rest and accelerates uniformly at +4.00 m/s squared for 10.0 seconds. What is its velocity after the
zavuch27 [327]
'  +4 m/s² ' means that the pigeon's speed is  4 m/s greater every second.

Starting from zero speed, after 10 seconds, its speed is 

                           (10 x 4m/s)  =  40 m/s.

We can't say anything about its velocity, because we have
no information regarding the direction of its flight.

A group of rescue workers is rescuing a dog from a condemned building. Due to demolition, the building has no stairs leading to
zaharov [31]

Answer:

Minimize the elevation or jump distance

Explanation:

The only action that minimizes, the impact force is to reduce as much as possible the height of the jump, the dog, ie the height from the jump point of the building. Since at the time of the jump its speed will increase every second at the rate of 9 [m/ s], that is this low effect of the gravitational acceleration of 9 [m/s^2]

v_{f}=\sqrt{2*g*h}

where:

vf = final velocity [m/s]

g = gravity [m/s^2]

h = elevation [m]

As we can see while there is higher height, at a higher speed will impact the ground.
