Answer:
The maximum height above the point of release is 11.653 m.
Explanation:
Given that,
Mass of block = 0.221 kg
Spring constant k = 5365 N/m
Distance x = 0.097 m
We need to calculate the height
Using stored energy in spring
...(I)
Using gravitational potential energy
....(II)
Using energy of conservation
Where, k = spring constant
m = mass of the block
x = distance
g = acceleration due to gravity
Put the value in the equation
Hence, The maximum height above the point of release is 11.653 m.
Answer:
Option A
Measures light from distant objects
Explanation:
A spectroscope is used to measure the use of light from a distant object to work out the object is made of.
It could be the single-most powerful tool astronomers use.
Professor Fred Watson from the Australian Astronomical Observatory says that "It lets you see the chemicals being absorbed or emitted by the light source"
Answer:
<em>The answer is C, a switch is set so an electrical charge cannot flow.</em>
Explanation:
In a transistor (working as a switch), 0 represents no flow of electricity; 1 represents electricity being allowed to flow
Weight=100N
SF=0.4
KF=0.3
Magnitude?
0.4 x 0.3 = 0.12
0.12x100=12
Ans =20
