What happens to a shopping cart if you get it rolling and then release it?

Physics
1 answer:
Anit [1.1K]3 years ago
7 0

Answer:

It will slowly come to a stop as long as it is moving on a flat surface

Explanation:

If the cart is moving on a flat surface, it will slowly come to a stop due to the friction forces acting on its wheels.

If the cart is on an inclined surface, it may gain acceleration enough to overcome any friction force, and thus continue with an accelerated motion.

In the chemical equation above, the small number after the O in 1202 represent —
Murrr4er [49]

Answer:

G.) The number atoms of that element in the molecule

Explanation:

F is incorrect because the coefficient represents the amount of one type of molecule, not the subscript

G is correct because subscripts represent how many atoms of that element are present in that single molecule

H is incorrect because energy is not represented in this simple type of equation

J is incorrect because it doesn't even make sense

What is the difference between resilience and modulus of resilience
pshichka [43]
<span>Resilience is the amount of energy that can be put into a volume of material and still be stored elastically. ie When the energy goes away, the material regains its undeformed shape. The Mod of R is the amount that can be stored by a unit volume of that material. The Mod of R is heavily related to Youngs Modulus.</span>

An electron is accelerated through 2400 V from rest and then enters a region in which there is a uniform 1.70 T magnetic field.
aalyn [17]

Answer:

Explanation:

Let v be the velocity acquired by electron in electric field

V q = 1/2 m v²

V is potential difference applied on charge q , m is mass of charge , v is velocity acquired

2400 x 1.6 x 10⁻¹⁹ = .5 x 9.1 x 10⁻³¹ x v²

v² = 844 x 10¹²

v = 29.05 x 10⁶ m /s

Maximum force will be exerted on moving electron when it moves perpendicular to magnetic field .

Maximum force = Bqv , where B is magnetic field , q is charge on electron and v is velocity of electron

= 1.7 x 1.6 x 10⁻¹⁹ x 29.05 x 10⁶

= 79.02 x 10⁻¹³ N .

Minimum force will be zero when electron moves along the direction of magnetic field .
