Your blood runs through your blood stream, every vein in your body. without that heartbeat the blood would not make it to the required places it needs to run to and you will lose oxygen and parts of your body and organs will shut down.
Connection to Big Idea about energy: Gravity creates gravitational potential energy. Gravitational energy relies on the masses of two bodies and their distance.
Connection to Big Idea about the universe: Gravitational force is exerted by all objects with mass throughout the Universe. It is what keeps the Earth and the planets in orbit around the Sun, and our Solar System in orbit around the centre of the Milky Way. Gravity is one of the forces involved in the birth of stars, their evolution and finally their death.
Connection to Big Idea about Earth: The gravitational force is responsible for many physical properties of Earth and consequently it affects the existence and the properties of living creatures on it. For instance, the existence, the chemical composition and the structure of Earth’s atmosphere was determined by Earth’s gravitational force.
Force on a moving charge is given by formula
here we know that this force will be maximum when velocity is perpendicular to magnetic field
here we know that
now we have
Answer:
Explanation:
We know that speed is defined as distance moved per unit time hence expressed as 
where v is speed in m/s, d is distance in m and t is time in seconds. Making d the subject of the above formula then
Substituting 343 m/s for d and 10 s for t then
Therefore, the distance between speaker and deter is
Answer:
The time-interval of the collision is 
Explanation:
As given the force is equal to the rate of change of momentum. Mathemticaly this is:
We can rearrange this equation to solve for 
which gives
which is our answer.
In words this means the time interval is equal to the momentum change in that interval divided by the force applied that caused this momentum change.
