Answer:
(1) weight = 565N
distance = 325m
time= 12.6s
power = work done/time
work done= force * distance
= 565*3.25 =1836.25
:. power = 1836.25\12.6
=145.7!
(2) the books will add more to her weight and thereby increasing her power output.
<h2>
Answer: destroy all information about its speed or momentum</h2>
The Heisenberg uncertainty principle postulates that the fact that <u>each particle has a wave associated with it</u>, imposes restrictions on the ability to determine its <u>position</u> and <u>speed</u> at the same time.
In other words:
<h2>It is impossible to measure <u>simultaneously </u>(according to quantum physics), and with absolute precision, the value of the position and the momentum (linear momentum) of a particle. </h2>
So, the greater certainty is seeked in determining the position of a particle, the less is known its linear momentum and, therefore, its mass and velocity.
It should be noted that this uncertainty does not derive from the measurement instruments, but from the measurement itself. Because, even with the most precise devices, the uncertainty in the measurement continues to exist.
Thus, in general, the greater the precision in the measurement of one of these magnitudes, the greater the uncertainty in the measure of the other complementary variable.
Answer and Explanation:
KUIPER BELT : The Kuiper belt is on the name of the scientist kuiper .It is the largest structure of the solar system its inner edge is about 30 AU from the Sun. The thickness of the kuiper belt is about 10 AU. It contains comets and other icy bodies
OORT CLOUD : The name of this cloud is one the name of a scientist Jhon oort. It is a theoretical cloud and mainly consist icy bodies it far away from the Sun. Its structure is spherical in nature and mostly contain ice water amonia methane
Answer:

Explanation:
Answer:
K.E is 2.25 J
Explanation:
Data :
Mass = m = 0.5 kg
Velocity = v = 3 m/s
Formula for K.E
K.E = 1/2mv²
Put values
K.E = 1/2(0.5)(3)² = 2.25 J
