Explanation:
The physics principle that goes to aerial spinning and twisting can be related to the conservation of angular momentum. ... Since momentum cannot be changed mid-air, he must decrease his rotational mass in order to increase his angular velocity. To increase his angular velocity the snowboarder tucks in his arms
Answer:
Mass of each objects, m = 185.69 kg
Explanation:
The gravitational force between two equal masses is,
Separation between the masses, d = 10 m
Let m is the mass of each object. The gravitational force is given by :
m = 185.69 kg
So, the mass of each objects is 185.69 kg. Hence, this is the required solution.
Power (P)= Voltage (V)* Current (I)
So I=P/V=12/9
I=1.3A
*This is a common answer of mine*
Hope this helps.
Answer:
3.67 km
Explanation:
Joe distance towards coffee shop is,
And the Max distance towards bookstore is,
Now the distance between the Joy and Max will be,
By applying pythagorus theorem,
Substitute 0.40 km for OB and 3.65 km for OA in the above equation.
Therefore the distance between there destination is 3.67 km.
Work done = Force(in direction of movement) x displacement
<span>Force from kinetic friction = friction coefficient x normal force. In this case the friction is acting antiparallel to the direction of motion with a force of 0.3 x 1.7 = 0.51N, again W=Fs, so work done on the box by kinetic friction = 0.51 x 1.8 = 0.918J</span>
