Answer:

The strong person should carry the ladder at the  front end and the weak person should carry it at the back end.

Explanation:

this is because in such a case the strong person has to pull the ladder whereas the weak person at the back end have to push the ladder. In such case it is easier to push because the weak person can use the force of gravity of his own body for pushing the ladde.

However in case of pulling the ladder one has to overcome his own gravity to pull the heavy object

Answer:

  weak person: near the end of the ladder

  strong person: nearer the center of the ladder

Explanation:

The closer the strong person is to the center of mass of the ladder, the greater the fraction of the ladder's weight that person will carry. The weak person will feel less weight if the strong person is nearer to the center of mass.

For example, if the strong person is 3/4 of the ladder's length from the end where the weak person is, then the strong person will carry twice the weight the weak person is having to carry. (Assuming the mass is uniformly distributed.)

Mass×acceleration of a triangle =force​
Law Incorporation [45]

Answer:

The force acting on a body is always equal to the product of the mass of the body and its acceleration.

Explanation:

The force of a body is defined as the product of mass and acceleration of the body.

According to Newton's second law, wherever there is a change in momentum of the body for an interval of time, there is a force acting on it.

                         F = (mv - mu) / t

                             = m (v -u) /t

                              = m a

Where,

                                 (v - u)/t - is the change in velocity of the body in the interval of time. It is equal to the acceleration of the body.

Hence, the equation for the force for any body becomes, F = m x a

1. What are the two factors affecting friction
bija089 [108]
Answer: a.) Roughness of the surfaces in contact with each other .
Higher the roughness of surfaces in contact with each other, greater is the friction between bodies. Force of friction will be less between smooth surfaces.

b.) Weight of the sliding/rolling body: greater the weight of the moving body on the surface, more is the force of friction on the body by the surface.

I hope this helps

Calculate the pressure in SI unit when a force of 100 dyne acts on area of 0.02cm²​
Andru [333]

Answer:

500 Pa

Explanation:

Convert given units to SI:

100 dyne = 0.001 N

0.02 cm² = 2×10⁻⁶ m²

Pressure = force / area

P = 0.001 N / (2×10⁻⁶ m²)

P = 500 Pa

Whitch best defines the relationship between speed and velocity
Neko [114]
Speed is a scalar quantity, meaning it has no direction. Velocity is a vector, meaning it has a specific direction associated with it.
