Explanation:
Answer:
M= -10/4
M = -5/2
-5/4 + m = -15/4
Explanation:
3/4 + m = -7/4
Subtract 3/4 from both sides
3/4 + m - 3/4 = -7/4 - 3/4
m = (-7-3) / 4
m = -10/4
m = -5/2
Check the options
11/4 + m = -1/4
m = -1/4 - 11/4
m = (-1-11) /4
m = -12/4
m = -3
-5/4 + m = -15/4
m = -15/4 + 5/4
m = (-15+5) /4
m = -10/4
m = -5/2
Answer:
The sun
Explanation:
if they get too close even the heat that radiates of of it would burn you or give sunburn bad and the sun is a shining ball of energy it is way to hot for a human to get close
Answer:
19.5°
Explanation:
The energy of the mass must be conserved. The energy is given by:
1) 
where m is the mass, v is the velocity and h is the hight of the mass.
Let the height at the lowest point of the be h=0, the energy of the mass will be:
2) 
The energy when the mass comes to a stop will be:
3) 
Setting equations 2 and 3 equal and solving for height h will give:
4) 
The angle ∅ of the string with the vertical with the mass at the highest point will be given by:
5) 
where l is the lenght of the string.
Combining equations 4 and 5 and solving for ∅:
6) 
Answer:
a. False
Explanation:
For an object to be moving at a constant velocity, a net force of 0 N would be required.
Newton's 1st Law of Motion states that an object will remain at rest unless acted upon by an unbalanced force, and an object will remain in motion unless acted upon by an unbalanced force.
Therefore, the unbalanced force of 6 N would not allow the rock to maintain its constant speed.
The answer to this question is A) False.
