Answer:
The acceleration of the block is 1.21 m/s².
Explanation:
Given that,
Mass = 2.0 kg
Force = 25.0 n
Angle = 30°
Coefficient of friction = 0.752
We need to calculate the acceleration of the block
Using balance equation
Put the value into the formula
Hence, The acceleration of the block is 1.21 m/s².
Answer:
Organic farming would have higher costs, and would be more complex than conventional farming. However, the Suarez family could charge a higher price for organic produce. This type of farming also would be better for the land.

Answer expert verified for the same question. (question/4178423)
Answer:
Explanation:
y_1 = (3 mm) sin(x - 3t)
comparing it with standard wave equation
y = A sin( ωt-kx )
we see
ω = -3 , k = -1
velocity = ω / k
= 3
y_2 = (6 mm) sin(2x - t)
we see
ω = -1 , k = -2
velocity = ω / k
= .5
y_3 = (1 mm) sin(4x - t)
we see
ω = -1 , k = -4
velocity = ω / k
= .25
y_4 = (2 mm) sin(x - 2t)
we see
ω = -2 , k = -1
velocity = ω / k
= 2
So greatest velocity to lowest velocity
y_1 = (3 mm) sin(x - 3t) , y_4 = (2 mm) sin(x - 2t) ,y_2 = (6 mm) sin(2x - t) , y_3 = (1 mm) sin(4x - t)
b )
Given the mass per unit length of wire the same , velocity is proportional to
√ T , where T is tension
so in respect of tension in the wire same order will exist for highest to lowest tension .
Answer:
1.88 N
Explanation:
h = 3.2 m, A = 0.6 cm^2 = 0.6 x 10^-4 m^2
density of water, d = 1000 kg/m^3, g = 9.8 m/s^2
Pressure at depth h, P = h x d x g = 3.2 x 1000 x 9.8 = 31.36 x 10^3 Pa
Force = pressure x Area = 31.36 x 10^3 x 0.6 x 10^-4 = 1.88 N
Thus, the force on ear drum is 1.88 N.
