Explanation:
Answer:
42.99°
Explanation:
= Kinetic friction force
= Pulling force at angle
= Weight of the box = 150 N
Kinetic friction force
Pulling force at angle
N = Pulling force
According to question
Applying Newton's second law in the vertical direction we get
The angle is 42.99°
Answer and Explanation:
In optics, a CoC(Circle of Confusion) is defined the minimum cross section of a paraxial bundle of rays made by a lens which is sphero-cylindrical type and can be viewed as an optical spot, which do not converge perfectly at the focus while a point source is being imaged due to spherical aberration.
The Circle of Confusion is also referred to as circle of indistinctness or a blur spot
Answer:
Mass, m = 71.42 kg
Explanation:
Given that,
Normal force acting on a box, F = 700 N
We need to find the mass of a box. Let it is m. Normal force acting on an object is balanced by its weight such that,
F = mg
Where m is the mass of the box
So, the mass of the box is 71.42 kg.
