Answer:
minimum distance will be 13.33 m
Explanation:
We have given the speed of both the car = 80 km/h
We know that 1 km =1000 m
And 1 hour = 60×60 =3600 sec
So
Reaction time is given as t = 0.60 sec
Minimum distance will be equal to the distance driver needed during reaction time
So minimum distance = u ×t =22.22 ×0.60=13.33 m
Her weight doesn't change but thats only simply because there is no gravity in space.
Answer:
The displacement is 20 m northward.
The distance is 44 m
Explanation:
Let northward motion be in positive direction
Let southward motion be in negative direction
Dispalcement is the shortest path covered by the hockey puck at a specified direction.
The dispalcement of the hockey puck will be calculated as;
Displacement = 26 m northward - 12m southward + 6 m northward
Displacement = 20 m in northward direction
Distance is the total path covered by the hockey puck.
Distance = 26 m + 12m + 6 m
Distance = 44 m
To solve this problem we will rely on the theorems announced by Newton and Coulomb about the Gravitational Force and the Electrostatic Force respectively.
In the case of the Force of gravity we have to,
Here,
G = Gravitational Universal Constant
= Mass of Proton
= Mass of Electron
d = Distance between them.
In the case of the Electric Force we have,
k = Coulomb's constant
= Charge of proton
= Charge of electron
d = Distance between them
Therefore
We can here prove that the statement is True
