<span>Good Morning!
The scientific advance that launched an ethical alert in the scientific community was the possibility of cloning animals, since it presents important questions, especially if such a project is extended to humans.

Answer:
0N
Explanation:
Parameters given:
Q1 = Q2 = Q3 = 100 * 10^(-9) C
r = 0.3 m
The net force on the middle charge is:
F = F(1,2) + F(2,3)
Where F(1,2) = force due to Q1 on Q2
F(2,3) = force due to Q3 on Q2
F(1,2) = k*Q(1)*Q(2)/r²
F(1,2) = [9 * 10^9 * 100 * 10^(-9) * 100 * 10^(-9)]/(0.3²)
F(1,2) = 0.001N
F(2,3) = k*Q(2)*Q(3)/r²
F(2,3) = [9 * 10^9 * 100 * 10^(-9) * -100 * 10^(-9)]/(0.3²)
F(2,3) = -0.001N
Therefore,
F = 0.001 - 0.001
F = 0N
1) they are attracting because if you look at the arrows they’re all pointing the same way.
2) if the magnet was turned around they would do the opposite and not attract ( this is called repulsion)
3) magnetic pole
4)magnet
5) magnetic force
6) magnetism
Hope this helps
Answer:A
Explanation:
Explanation:
Given that,
Gravitational force = 600 N
Frictional force = 25 N
Pulled by the Force = 250 N
We know that,
The gravitational force in downward and normal force act in upward. the frictional force in left side and the box pulled by the force to the right side.
The balance equation is along y-axis
The box will not move in y-axis therefore, the net force in the y-axis will be zero.
Hence, The net force in the y-direction will be zero.
Answer:
a) True
b)False
c)False
• Had to complete the question first.
A block slides at constant speed down a ramp while acted on by three forces: its weight, the normal force, and kinetic friction. Respond to each statement, true or false.
(a) The combined net work done by all three forces on the block equals zero.
(b) Each force does zero work on the block as it slides.
(c) Each force does negative work on the block as it slides.
Explanation:
Net work is the change in kinetic energy, which leads to final kinetic energy - our initial kinetic energy this is the formula for net work. This is the working energy theorem, a theorem that states that the net work on an object induces a change in the object's kinetic energy.
