A 2.5 m segment of wire supplying current to the motor of a submerged submarine carries 1050 A and feels a 3.6 N repulsive force
Zanzabum

force between two parallel wire is

f/l = mueo*i1i2/2pir

f/l = 2*10^-7*i1i2/rl

i2 = f*r/2*10^-7*i1

i2 = 342.9 A

Please help! A net force of 2.0 N acts on a 2.0-kg object for 10 seconds. What is the object’s kinetic energy after that 10 seco
padilas [110]
For Newton's second law, the force F applied to the object of mass m will cause an acceleration a of the body:
F=ma
So, the acceleration is 
a= \frac{F}{m}= \frac{2.0 N}{2.0 kg}=1 m/s^2

The object undergoes through this acceleration for 10 seconds, t=10 s. Since it is an accelerated motion, we can find its final velocity after 10 seconds:
v_f = v_i + at=0 m/s+(1m/s^2)(10 s)=10 m/s
where v_i is the initial velocity of the object, which is zero since it starts from rest.

Finally we can calculate the final kinetic energy of the object, which is given by
K= \frac{1}{2}mv^2= \frac{1}{2}(2.0 kg)(10 m/s)^2=100 J

What describes why ocean currents are considered convection currents
ratelena [41]

Convection occurs because the oceanic waters heat up becoming less dense. This water moves above the cooler water, and give off its heat to the surrounding environment. As it cools, it begins to sink, and the process begins again.

ludmilkaskok [199]

If a surplus exists, then quantity demanded is less than quantity supplied, there will be pressure on price fall toward equilibrium.

When the quantity of supply of goods matches the demands for goods, it is called the equilibrium price. The market is said to be in a state of equilibrium when the main situation is in the phase of consolidation. Then, it can be concluded that demand and supply are comparatively equal. Equilibrium price examples are discussed below as well.

We can find the equilibrium price by using the equilibrium price formula. These are the steps:

  • Calculate the supply function,
  • Calculate the demand function,
  • Set the equal amount of quantities for the demand and supply,
  • Put this equilibrium price into a supply function,
  • Check the result by putting the equilibrium price into the demand function.

A surplus implies the government has extra funds. These funds can be used toward public debt, to start new events, social service or Medicare service and also in reducing interest rates which can help the economy.
