Turbine transformer generator⇆
Answer:
60N
Explanation:
According to the principle of lever: a torque can control if an object will spin or not.
The torque Iskander cause is 40*1.2=48 N-m
So for balanced, Danny should cause the same torque.
48/0.8=60, Danny weigh 60N.
(a) The magnitude of the net force on the crate is -26.46 N.
(b) The net work done on the crate while it is on the rough surface is -17.2 J.
(c) The speed of the crate when it reaches the end of the rough surface is 0.61 m/s.
<h3>Magnitude of net force on the crate</h3>
The magnitude of the net force on the crate is calculated as follows;
F(net) = F - Ff
where;
F(net) = F - μmg
F(net) = 290 - (0.351)(92)(9.8)
F(net) = -26.46 N
<h3>Net work done on the crate</h3>
W = Fd
W = -26.46 x 0.65 = - 17.2 J
<h3>Speed of the crate </h3>
acceleration of the crate, a = F/m
a = -26.46/92
a = -0.288 m/s²
v² = u² + 2as
v² = 0.865² + (2)(-0.288)(0.65)
v² = 0.374
v = 0.61 m/s

Answer:
electrons are completely transferred from one atom to another. In the process of either losing or gaining negatively charged electrons, the reacting atoms form ions. The oppositely charged ions are attracted to each other by electrostatic forces, which are the basis of the ionic bond.
