Answer:
A ) 1000 m.
Explanation:
Here initial velocity u = 100 m /s
Final velocity v = 0
Acceleration a = -5 ms⁻²
Distance travelled = S
v² = u² + 2aS
0 = (100)² -2 x 5 S
S = 10000/ 10
=1000 m.
<u>Answer</u>:
D. Entropy is a measure of disorder or randomness
<u>Explanation</u>:
The answer is entropy. It is the method to measure any disorder or randomness of any system. Basically it is concept of physics and chemistry but can also be used in other subject matters as well. In formula terms, it is denoted by S and is measurement value is "Joule per kelvin". The values could be both positive and negative as well.
All the other options are incorrect as heat, energy and temperature are the different concepts of science which do not relates with any measurement.
A) 330 N
Explanation: Her weight must be evenly distributed between the chains (assuming they are at an even level), so you divide 660 by 2 and get 330
Answer:
the answer is the last one
Explanation:
here is the definition:
(i know how to explain the answer, its merely unnecessary being that there is an offical definition.)
<em>the series of processes by which carbon compounds are interconverted in the environment, involving the incorporation of carbon dioxide into living tissue by photosynthesis and its return to the atmosphere through respiration, the decay of dead organisms, and the burning of fossil fuels.</em>
Option (B) is correct.The magnetic field strength=8.5 x 10² T
Explanation:
the magnetic force Fm is given by
Fm= q V B sinθ
q= charge=1.4 x 10⁻⁷ C
v= velocity= 1.3 x 10⁶ m/s
B= magnetic field strength
Fm= magnetic force= 1.5 x 10² N
θ=75°
so 1.5 x 10²=(1.4 x 10⁻⁷) (1.3 x 10⁶ ) (B) sin75
B=8.5 x 10² T
