Answer:

Explanation:

Let the amplitude of individual wave be I and resultant amplitude be 1.703 I . Let the phase difference be Ф in terms of degree

From the formula of resultant vector

(1.703I)² = I² + I² +  2 I² cosФ

2.9 I² = 2I² + 2 I² cosФ

.9I² = 2 I² cosФ

cosФ = .9 / 2

= .45

Ф = 63.25 .

From Clausius theorem we get the formula for the change of entropy:
dS=\frac{dQ}{T}
dS is the change of entropy, dQ is the change of energy, and T is the temperature in Kelvin.
We need to convert those temperatures:
T_{in}=22^\circ C= 273.15+22=295.15K\\ T_{out}=-17.5^\circ C=273.15-17.5=255.65K
Entropy changes inside and outside:
$$Inside$: dS= \frac{-dQ}{T_in}=\frac{-20\cdot 10^3}{295.15K}=-67.76\frac{J}{K}
$$Outside$: dS= \frac{+dQ}{T_out}=\frac{+20\cdot 10^3}{255.65K}=+78.23\frac{J}{K}
The net entropy increase is:
dS=+78.23\frac{J}{K}-67.76\frac{J}{K}=+10.47\frac{J}{K}

If a net horizontal force of 175 N is applied to a bike whose mass is 50 kg what acceleration is produced?
Crazy boy [7]

The acceleration of the bike is 3.5 m/s^2

Explanation:

We can solve this problem by using Newton's second law of motion, which states that:

F=ma

where

F is the net force on an object

m is the mass of the object

a is its acceleration

For the bike in this problem, we have

F = 175 N is the net force

m = 50 kg is the mass

And solving for a, we find the acceleration:

a=\frac{F}{m}=\frac{175}{50}=3.5 m/s^2

vlada-n [284]

Answer:

Work done by friction along the motion is given as

W_f = -5857.8 J

Explanation:

As per work energy theorem we can say

Work done by all forces = change in kinetic energy of the system

so here car is moving from bottom to top

so here the change in kinetic energy is total work done on the car

so here we will have

W_f + W_g = \frac{1}{2}m(v_f^2 - v_i^2)

W_f - mgH = \frac{1}{2}m(v_f^2 - v_i^2)

now plug in all data in it

W_f - (130)(9.81)(2\times 12) = \frac{1}{2}(130)(8^2 - 25^2)

W_f = 30607.2 - 36465

W_f = -5857.8 J

Why blue light elicits a positive phototropic?
kodGreya [7K]
Phototropism is the growth of an organism which responds to a light stimulus. It is most often observed in plants, but can also occur in other organisms such as fungi. The cells on the plant that are farthest from the light have a chemical called auxin that reacts when phototropism occurs. This causes the plant to have elongated cells on the farthest side from the light.
