Answer:
unbalanced force
Explanation:
According to Newton the determining factor on if and how an object will move is the unbalanced force acting upon that object. In Newton's first law he states that an object will remain at rest unless acted on by an unbalanced force. This unbalanced force needs to be stronger than any opposite force being acted upon by the same object. Enough so that the object exits its state of rest and begins moving in the direction in which the force is being applied. If the force is not strong enough to overcome the opposite forces then the object will not move.
Answer:
He went to the University of Pisa at 16. He discovered the four most massive moons of Jupiter, now known as the Galilean moons.
Explanation:
Centripetal force is given by F= mv²/r.
Given: m = 0.5 kg, v = 3 m/s, r = 0.5 m
Putting values,
F= mv²/r = 0.5× 3²/0.5 = 9 N
Answer:
A 1 horsepower motor with 75% effiency will require 994. 26 watt
Explanation:
To calculate the effiency, 1 horsepower is equivalent to 745.7 watts
1hp= 745.7 w
So, by using a rule of three the calculation its like this:
745.7 ⇒ 100%
X ⇒ 75%
The information about the volts in this example is not required, but it can be used to calculate the current.
You can determine wavelength with “x”
