Ashear force of 400 n is applied to one face of an aluminum cube with sides of 30 cm. what is the resulting relative displacement? (the shear modulus for aluminum is 2.5 x 1010n/m2).

a) 4.4 x 10-8 m
b) 8.2 x 10-8 m
c) 1.9 x 10-8 m
d) 5.3 x 10-8 m

So option (d) will be correct option

Explanation:

We have given shear force F = 400 N

Size of the cube

Shear modulus of aluminium

We have to find the resulting relative displacement

Area of the cube

We know that shear force is given by

So

So option (d) will be correct option

answer: d. a cme increases the amount of energy in the solar wind

explanation:

coronal mass ejections, also called cmes, are large clouds of plasma and magnetic field that erupt from the sun. only when the cloud is aimed at earth will the cme hit earth and therefore cause impacts. high-speed solar wind streams come from areas on the sun known as coronal holes.

weather forecasts are done by collecting data about the current state of the atmosphere mainly the temperature, humidity and wind and using meteorology, to determine the atmosphere that evolves over time. the h and l mean the high and low pressure. the red strip is a warm front. the blue strip is a cold front. the blue and red strip is a stationary front. the purple strip is a occluded front.
