When cleaning up a local beach, students found many different particles that were in the water that affected the shoreline, like

litter and gasoline. Which of the following describe how these items would need to separated from the water? Why? Question 5 options: Litter would need to be physically separated with water and gasoline would need to be chemically separated from water, because both form a mixture with the water. Both gasoline and litter would need to be physically separated from the water, because neither bonds with the water. Both gasoline and litter would need to be chemically separated from the water, because both form new bonds with the water. Both gasoline and litter would need to be chemically separated from the water, because neither bonds with the water.

Does the magnetic force on the longer sides of the generator loop help or hinder the rotation of the generator loop?
Ilia_Sergeevich [38]

Answer:

Help

Explanation:

We can observe using Fleming's right hand rule that magnetic field line are perpendicular to longer arms and parallel to the shorter arms. Therefore, magnetic force on the long arm will help the rotation of the generator rather than hindering it. No force on the shorter arm as they are parallel to the field lines.

One number is 9 more than twice another number. if the sum of the number is 129, find both numbers.
Paladinen [302]

Let's call the first number n, and the second number m.

n = 2m + 9 (9 more than twice the second number)

If the sum is 129, that means n + m = 129.

Now we can substitute the first expression (n = 2m + 9) into the second expression (n + m = 129), replacing the n.

(2m + 9) + m = 129

3m + 9 = 129

3m = 129 - 9

3m = 120

m = 120/3

m = 40

Now that we know m, we can find out n by replacing the m with 40 in the first expression (n = 2m + 9):

n = 2(40) + 9

n = 80 + 9

n = 89.


Therefore, n = 89, and m = 40.

The force needed to keep a car from skidding on a curve varies inversely as the radius of the curve and jointly as the weight of
motikmotik

Explanation:

It is given that, the force needed to keep a car from skidding on a curve varies inversely as the radius of the curve and jointly as the weight of the car and the square of the car's speed such that,

F\propto \dfrac{mgv^2}{r}

F=\dfrac{kmgv^2}{r}

mg is the weight of the car

r is the radius of the curve

v is the speed of the car

Case 1.

F = 640 pounds

Weight of the car, W = mg = 2600 pound

Radius of the curve, r = 650 ft

Speed of the car, v = 40 mph

640=\dfrac{k(2600)(40)^2}{650}

k = 0.1

Case 2.

Radius of the curve, r = 750 ft

Speed of the car, v = 30 mph

F=\dfrac{0.1\times 2600\times (30)^2}{750}

F = 312 N

Hence, this is the required solution.
