Answer:

Torque = 0.25Nm

Explanation:

To calculate the magnitude of torque, first we must calculate the lever arm. The lever arm is perpendicular distance from the axis of rotation to the line of the action of the force.

Lever arm = r sin theta

Where r = 4.9cm= 0.049m

Theta = 30°

Lever arm = 0.049 sin30° = 0.245m

Magnitude of torque = rfsintheta

f = 1.0T

Magnitude of torque= 0.245×1.0 = 0.245Nm

To 2 significant figure=0.25Nm

Answer:

Hello your question has some missing parts attached below is the complete question

answer : 4 μm

Explanation:

since the scale bar works the same way as a scale on a map , each bar will therefore represent 1 μm and the mature parent cell's is about 4 times the labeled value hence the Mature parent cell diameter will approximately be : 4 μm

WORTH 10 POINTS! I WILL GIVE BRAINLIEST!
Sav [38]

Answer:

The Sun’s magnetic field, solar winds and the Earth's magnetic tail are responsible for making the aurora lights in the north and south poles look different, say international scientists. Researching the interactions of these phenomena have debunked previous theories around why the lights can have different shapes and can occur in different locations. This research also helps scientists to better understand the interactions between the sun and earth, which could help with predicting space weather.

How can you verify the archimedes principle?​
Ipatiy [6.2K]

Answer:

It is found that W1 - W2 loss in weight of solid when immersed in water is equal to the weight of the water displaced by the body. This verifies Archimedes' principle.
