If 2.0 j of work Is done raising a 180 g Apple how far was it lifted

Physics
1 answer:
andrew11 [14]3 years ago
6 0

The apple is lifted by 1.1 m

<u>Explanation</u>:

  • Given that, mgh = 2 J and mass of apple = 180g
  • Step 1: convert grams to kg as work is given in SI units.

                    180 g = 0.18 kg

  • Step 2: substitute in the formula for work done.

                    0.18 * 10 * h = 2

  • Step 3: calculate the value of h from this formula.

                      h = 2/1.8

                      h = 1.11 m

ou have designed and constructed a solenoid to produce a magnetic field equal in magnitude to that of the Earth (5.0 10-5 T). If
Nikitich [7]

Answer:

I = 0.0256 A

Explanation:

Given,

Magnetic field, B = 5 x 10⁻⁵ T

Number of turns, N = 450

length = 29 cm

Current,I = ?

Using formula of magnetic field due to solenoid

B = \mu_0 NI

I = \dfrac{B}{\mu_0N}

I = \dfrac{5\times 10^{-5}\times 0.29}{450\times 4\pi \times 10^{-7}}

I = 0.0256 A

Hence, the current obtained is equal to 0.0256 A.

With what maximum precision can its position be ascertained? [hint: ?p=m?v.]
Nana76 [90]
The formula for the momentum is
p = mv
As a consequence of the conservation of energy, there is also the law of conservation of momentum.
So,
Δp = Δmv = mΔv
The maximum precision that the position can be ascertained is less than 100% because of dissipation.

Convert 23 miles into feet.<br> **There are 5280 feet in 1 mile** *
zhenek [66]

Answer:

121440 feet is 23 miles.

5280 x 23= 121440

To check your answer just divide 121440 by 5280, which gives you 23.

Hopefully this helps you!

Consider the system consisting of the box and the spring, but not Earth. How does the energy of the system when the spring is fu
BabaBlast [244]

Answer:

the energy when it reaches the ground is equal to the energy when the spring is compressed.

Explanation:

For this comparison let's use the conservation of energy theorem.

Starting point. Compressed spring

         Em₀ = K_e = ½ k x²

Final point. When the box hits the ground

         Em_f = K = ½ m v²

since friction is zero, energy is conserved

          Em₀ = Em_f

          1 / 2k x² = ½ m v²

          v = \sqrt{ \frac{k}{m} }     x

Therefore, the energy when it reaches the ground is equal to the energy when the spring is compressed.
