London, it has hosted the 1908, 1948 and the 2012 summer olympics
Answer:
<span>5010J</span>
Explanation:
Work is force times distance, or
<span>W=F⋅d</span>.
Substitute in values from the question to get
<span>W=8.35⋅<span>102</span>N⋅6m=50.1⋅<span>102</span>Nm=5010<span>J</span></span>
Answer:
The fraction of the total energy goes into kinetic energy of proton is 
Explanation:
Given:
Mass of proton 
Mass of electron 
kg
Here neutron at rest decays into proton and electron
⇄ 
Where 
energy released
The 
value of this reaction is given by
Where 
kinetic energy of reaction
Here we need to find fraction of the total energy released goes into the kinetic energy of the proton
Therefore, the fraction of the total energy goes into kinetic energy of proton is
F = applied force on the wheelbarrow in forward direction = 600 N
f = frictional force pushing in backward direction of wheelbarrow = ?
m = mass of the wheelbarrow = 28 kg
Since wheelbarrow moves forward at a constant velocity
a = acceleration of the wheelbarrow in forward direction = 0 m/s²
force equation for the motion of wheelbarrow in forward direction is given as
F - f = ma
inserting the above values in the formula
600 - f = (28) (0)
600 - f = 0
f = 600 N
hence the frictional force comes out to be 600 N
velocity describes speed with direction.
