Answer:
Physical sciences are those academic disciplines that aim to uncover the underlying laws of nature - often written in the language of mathematics. It is a collective term for areas of study including astronomy, chemistry, materials science and physics.
Explanation:
Answer:
1.152 miles
Explanation:
Given: central angle = 1 minute = 
radius of the earth = 3960 miles
The length of an arc =
2
r
where:
is the central angle, and r is the radius.
Thus,
Distance along the arc =
2
r
Distance along the arc =
x 2 x
x 3960
=
x 24891.4286
= 1.1524
The required distance along an arc is 1.152 miles.
X =0.75,2 i hope this helps you
a mechanical wave is a wave that is an oscillation of matter, and therefore transfers energy through a medium. while waves can move over long distances, the movement of medium transmission-the material- is limited. again, the oscillating material does not move far away from its initial equilibrium position ;)
Answer:
D
Explanation:
From the information given:
The angular speed for the block 
Disk radius (r) = 0.2 m
The block Initial velocity is:

Change in the block's angular speed is:

However, on the disk, moment of inertIa is:

The time t = 10s
∴
Frictional torques by the wall on the disk is:

Finally, the frictional force is calculated as:
