Answer:

N = Mg cos\theta

Explanation:

As we know that the block is placed on the inclined plane

So here we know that the components of weight of the block are

F_x = Mgsin\theta along the inclined plane

above component of the weight will be counter balanced by friction force as it will be at rest

F_y = Mgcos\theta perpendicular to the inclined plane

above component is perpendicular to inclined plane surface and it will be counter balanced by the normal force

So here correct answer for normal force will be

N = Mg cos\theta

Difference between output work and input work​
Harrizon [31]

An input device sends information to a computer system for processing, and an output device reproduces or displays the results of that processing. Input devices only allow for input of data to a computer and output devices only receive the output of data from another device.

Hope it helps!

Answer:

daughters cells

Explanation:

when people refer to “cell division,” they mean mitosis, the process of making new body cells. Meiosis is the type of cell division that creates egg and sperm cells. Mitosis is a type of cell division in which one cell (the mother) divides to produce two new cells (the daughters) that are genetically identical to itself.

Manuel is holding a 5 kg box. How much force us the box exerting on him? in what direction
Free_Kalibri [48]
It will be 49 Newtons of force in the down direction. To find the force in newtons, you multiply the mass (5 kg) by the gravity (which if 9.8).
