Answer:
5.3 × 10^(-8) m
Explanation:
We are given;
Shear force; F = 400 N
Length of cube; L_o = 30 cm = 0.3 m
Shear modulus; S = 2.5 × 10^(10) N/m²
Now,the resulting relative displacement can be gotten from the formula;
F = A × S × Δx/L_o
Where Δx is resulting relative displacement
A is area.
Area of cube = (L_o)² = 0.3² = 0.09
Thus, making Δx the subject, we have;
Δx = (F × L_o)/(A × S)
Plugging in the relevant values;
Δx = (400 × 0.3)/(0.09 × 2.5 × 10^(10))
Δx = 5.3 × 10^(-8) m
Answer:
The force is
Explanation:
Given that,
Diameter = 7.55 mm
Intensity of light = 3.87 kW/m²
Angle = 19.9°
Intensity of absorbed light
Intensity of incoming light
Ratio of intensities
Relation between intensity and power
...(I)
The power is
....(II)
From equation (I) and (II)
Put the value into the formula
Hence, The force is
Both physicians Einstein and Newton explained the gravity.
Einstein described the gravity by suggesting that the space-time around any object is bent, while Newton described gravity by principle of action.,
