Answer:
D
Explanation:
transparent_objects that allows light to pass through and can you see through them
We know from Newtons law of force that
Work done = Force * Distance moved
We know from the question that
Force applied = 70 Newton
Distance moved = 9 meters.
Since the object is moving in the same direction as the force applied
So
Work done = Force * Distance moved
= 70 * 9 newton meters(Nm)
= 630 newton meters(Nm)
= 630 joules
Answer: The mass of the sculpture is 11.8kg
Explanation:
Using the equation of fundamental frequency of a taut string.
f = (1/2L)*√(T/μ) .... (Eqn1)
Where
f= frequency in Hertz =80Hz
T = Tension in the string = Mg
M represent the mass of the substance (sculpture) =?
g= 9.8m/s^2
L= Length of the string=90cm=0.9m
μ= mass density = mass of string /Length of string
mass of string =5g=0.005kg
L=0.9m
μ=0.005/0.9 = 0.0056kg/m
Using (Eqn1)
80= 1/(2*0.9) √(T/0.0056)
144= √(T/0.0056)
Square both sides
20736= T/0.0056
T= 116.12N
Recall that T =Mg
116.12= M * 9.8
M=116.12/9.8
M= 11.8kg
Therefore the mass of the sculpture is 11.8kg
