The currents responsible for powering the movement of tectonic plates is convection currents which occur in the mantle. As the hotter, less dense liquid rises it displaces the cooler more dense liquid which moves the tectonic plates out of allignment

Certain suv ads claim that their vehicles can climb a slope of 45?. what is the minimum coefficient of static friction between t

kotykmax [81]

First, you make a force body diagram to illustrate the problem. Then, apply Newton's laws of motion.

Summation of forces along the y-direction:

F = 0 (bodies at equilibrium) = Normal force - weight*cos45 = 0
Normal force = wcos45

Summation of forcesalong the x-direction:

F = 0 (bodies at equilibrium) = Frictional force - weight*sin45 = 0
x*Normal force - weight*sin45 = 0 (let x be the min coeff of static friction)
x*weight*cos45 = weight*sin 45
x = sin45/cos45 = 1

Therefore, the minimum coefficient of static friction must be 1.

A coil of wire has been wrapped into a circle of 100 times with a diameter of 2.0 m. The coil is placed in a magnetic field of 5

jek_recluse [69]

Answer:

1570 V

Explanation:

N = 100

diameter = 2 m

radius = 1 m

B = 5 tesla

initailly the angle between the area vector of the coil and the magnetic field is zero and then the angle becomes 180 degree.

t = 2 s

Let Φ be the initial magnetic flux.

Φ = B A Cos 0 = 5 x 3.14 x 1 x 1 x 1 = 15.7 Wb

Let Φ' be the final magnetic flux

Φ' = B A Cos 180 = - 5 x 3,14 x 1 x 1 x 1 = - 15.7 Wb

According to the law of electromagnetic induction, the induced emf developed is equal to the rate of change of magnetic flux linked with the coil.

$e = -N\frac{d\phi }{dt}=\frac{\phi '-\phi }{t}$

$e =-100\frac{-15.7-15.7}{2}=1570 V$

Three cars, car x, car y, and car z, begin accelerating from rest, at the same time. car x is more massive than car y, which is

grigory [225]

When the net force exerted on each car is identical. after 10 seconds, the amount of momentum is same for all cars.

<h3>What is impulse?</h3>

The change in momentum is equal to the product of impact force applied while colliding and time for that impact.

F. t = m (Vf -Vi)

where, Vf is the final velocity and Vi is the initial velocity.

For car X, Fx x t = Mx Vx

For car Y, Fy x t = My Vy

For car Z, Fz x t = Mz Vz

The force applied is same for all and the the time is also same equal to 10 seconds. The impulse is same for all the cars.

Thus, the three cars have same momentum.
