A 5c charge experiences a force of 40n when put at a certain location in space. What is the electric field at that location?

1 answer:

3 0

The 'strength' of the electric field is the force on 1C of charge at that point.

At this 'certain location', the field is 40/5 = 8 newtons per coulomb = <u>8 volts</u>

the speed of a tortoise and a hare are 1m/s and 3m/s. the mass of hare is 5kg and the tortoise is 20kg. which has greater moment

Novosadov [1.4K]

Answer: tortoise

Explanation:

Given the following :

Speed of tortoise = 1m/s

Speed of hare = 3m/s

Mass of hare = 5kg

Mass of tortoise = 20kg

Momentum = product of Mass and velocity

Momentum of hare = mass of hare × Velocity of hare

Momentum of hare = 5kg × 3m/s = 15kgm/s

Momentum of tortoise = mass of tortoise × Velocity of tortoise

Momentum of tortoise = 20kg × 1m/s = 20kgm/s

Therefore, tortoise has a greater momentum than hare.

How do i find stretch? The problem in questioning has already given me the elastic energy and k-value, but I have no idea how to

finlep [7]

Answer:

Stretch can be obtained using the Elastic potential energy formula.

The expression to find the stretch (x) is $x=\sqrt{\frac{2\times EPE}{k}}$

Explanation:

Given:

Elastic potential energy (EPE) of the spring mass system and the spring constant (k) are given.

To find: Elongation in the spring (x).

We can find the elongation or stretch of the spring using the formula for Elastic Potential Energy (EPE).

The formula to find EPE is given as:

$EPE=\frac{1}{2}kx^2$

Rewriting the above expression in terms of 'x', we get:

$x=\sqrt{\frac{2\times EPE}{k}}$

Example:

If EPE = 100 J and spring constant, k = 2 N/m.

Elongation or stretch is given as:

$x=\sqrt{\frac{2\times EPE}{k}}\\\\x=\sqrt{\frac{2\times 100}{2}}\\\\x=\sqrt{100}=10\ m$

Therefore, the stretch in the spring is 10 m.

So, stretch in the spring can be calculated using the formula for Elastic Potential Energy.

What does the force of gravity between two objects depend on?

lawyer [7]

-- The equal, mutual forces of gravity between two objects depend on the product
of the two masses ... it doesn't matter whether the masses are equal or there's
one huge mass and one minuscule mass. It's the product that counts.

-- The force also depends on the distance between the centers of the two objects.
