The answer is: Electromagnet.
Electromagnets are magnets that are powered by a battery. You can usually find them in generators.
Answer:
Probably 2 But it might be 1 :)
Explanation:
Answer:
Explanation:
In order to solve this problem, we will need to draw a free body diagram of both situations (see attached picture).
So first, we need to find what the mass of the object is. We can do so by analyzing the horizontal movement of the first situation, so we get:
F=ma
so
m=2.34kg
next, we can analyze the second situation, we will start by analizing the vertical movement so we can determine the Normal force, so we get:
N=W
N=mg
N=3.79N
so now we can analyze the horizontal movement of the block, so we get:
Answer:
two forces are acting in opposite directions on an object, and they are equal in size.
Answer:
The angular distance in revolution is
The angular distance in radians is
The angular distance in degrees is
The angular size is
Explanation:
From the question we are told that
The diameter is
The distance moved by the rim is
Generally the circumference of the pie plate is mathematically represented as
Substituting the values
The number resolution carried out by the pie plate is evaluated as
Substituting value
The angular distance is mathematically evaluated as
Where r is the radius which is mathematically evaluated as
Substituting this into the equation for angular distance
The angular distance traveled in degrees is
When the pie is cut into 9 equal parts
The angular size would be mathematically evaluated as
