Answer:
W = F * s
Work done equals applied force * distance traveled
Apparent weight = M g (1 - sin θ) since some of applied force will lighten sled
μ = coefficient of kinetic friction
F cos θ = force applied to motion of sled
s = distance traveled
[μ M g (1 - sin θ)] cos θ * s = work done in moving sled
Note that F = μ M g if applied force is in the horizontal direction
Technology makes us feel more alone because we are more dependent on social media connections than real life connections. Simply put, technology-independent architecture means not being biased towards any particular platform or software language.
Answer:
yes, the potential difference across the terminals of the battery can be equal to its emf.
Explanation:
when the current in the battery is zero, meaning the current though, and hence the potential drop across the internal resistance is zero. This only happens when there is no load placed on the battery.
Answer:
Explanation:
the momentum of a body is defined as the product of mass of body and the velocity f the body.
P = m x v
Where, m is the mass and v be the velocity of the body.
it is a vector quantity and its unit is newton second.
When the velocity of the object is zero, the momentum is also zero.
Newtons' first law states that the body is at rest or in motion , it remains at rest or in motion until and unless an external force is not applied on the body.
So, When a body is at rest it remains at rest.
