Jared is experimenting with a force that is attractive only and the weakest of the fundamental forces. He is experimenting with

yawa3891 [41]

Jared in experimenting with the Gravitational Force. It is considered to be the weakest of the four fundamental forces, Strong nuclear force as the strongest, this the force that binds the nucleus of an atom. Next would be the Electromagnetic Force which deals with the movements of electrons. Third would be the weak nuclear force, which deals with the radioactivity and decay. In measuring the relative strength, strong nuclear force would be at 1. Electromagnetic would be at 10^-3, Weak Nuclear force is at 10^-13 and the weakest gravitational force is at 10^-40.

3. An object of mass m is moving with a speed of v0 to the right on a horizontal frictionless surface, when it explodes into two

Naily [24]

Answer:

The speed of the other piece of the object is 13/4*v0, going to the right.

Explanation:

Assuming that no external forces acting during the explosion (as the time during which it happens is considered infinitesimal), total momentum must be conserved , same as it happens with the total mass, assuming that v₀ is much smaller than c (speed of light), so no conversion of mass into energy is done.

So, based on the information provided, we can write the following expression, assuming the positive direction to be the one to the right:

m*v₀ = -3/5*m*(v₀/2) + 2/5*m*vₓ

Solving for vₓ, we have:

vₓ = 13/4*v₀, to the right, as the value obtained is positive.

The linear density of a string is 1.9 × 10-4 kg/m. A transverse wave on the string is described by the equation y = (0.034 m) si

garri49 [273]

Answer:

a. v = 13.572 m / s

b. T = 2.578 x 10 ⁻³ N

Explanation:

μ = 1.9 x 10 ⁻⁴ kg / m

y = y ₙ * sin ( kx + wt )

y = 0.034 m * sin ( 2.8 m⁻¹) x + (38 s⁻¹)t

R = 2.8 m⁻¹

W = 38 s⁻¹

To determine speed of the string

v = W / R = 38 / 2.8

v = 13.572 m / s

v = √ T / μ

v ² = T / μ

To determine the tension on the string

T = v ² * μ

T = 13.572 m/s * 1.9 x 10 ⁻⁴ kg / m

T = 2.578 x 10 ⁻³ N

Several teenagers swim toward a rectangular, wooden raft that is 2.00 m wide and 2.50 m long. If the raft is 9.80 cm thick, how

densk [106]

Answer:

Explanation:

length of the raft, L = 2 m

Width of the raft, W = 2.5 m

height of the raft, H = 9.8 cm = 0.098 m

mass of each person, m = 75 kg

Density of wood = 650 kg/m^3

volume of raft, V = L x W x H = 2 x 2.5 x 0.098 = 0.49 m^3

let there are N persons

According to the principle of floatation

Buoyant force acting on the raft = True weight of the raft

Volume x density of water x g = volume x density of wood x g + N x mg

0.49 x 1000 x g = 0.49 x 650 x g + N x 75 x g

490 = 318.5 + N x 75

N = 2.28

So, the maximum number of person is 2.
