Which one of the following SI base units is not matched to the correct unit of measurement? A. Mass: kg
B. Time: s
C. Length: km
D. Temperature: K
Answers
Answer:
C. Length: km
Explanation:
Let's analyze each option:
A. Mass: in the SI system, mass is measured in kilograms (kg), so this matching is correct.
B. Time: in the SI system, time is measured in seconds (s), so this matching is correct.
C. Length: in the SI system, length is measured in meters (m). The kilometer, instead, is a multiple of the meter (). Therefore, this matching is not correct.
D. Temperature: in the SI system, temperature is measured in Kelving (K), so this matching is correct.

Answer:
The distance travelled is 2.34*10^8 m.
Explanation:
The acceleration of the spacecraft is,
a=F/m
=391/7870 = 0.04968 m/s^2
The distance travelled,
d=v^2-v0^2/2a
=(4820)^2-(38)^2 / 2(0.04968)
=2.34*10^8 m.
B. The entire universe.

Answer:
Distance
Explanation:
Isometry preserves the distance while transformation is made in between metric spaces. When a metric space is mapped on to another or itself, the distance between two points remains same in the images in the mapped space as well. Example: rotation and translation.
Thus, isometry preserves the distance.

Explanation:
Vitamins are the organic compounds which are necessary for normal growth and provide nutrition to the body.
Vitamins help in conversion of food into energy and repair cellular damage.
For example, Vitamin C helps in boosting immune system. Vitamin B6 helps in the biochemical reactions occurring in the immune system.
Thus, we can conclude that out of the given options, the statement Vitamins help produce the immune response is most accurate.
The most accurate statement about vitamins is vitamins help produce the immune response. (Option A)
What are the functions of vitamins?
Vitamins play a crucial role in supporting the immune system by promoting the production and functioning of immune cells, aiding in the synthesis of antibodies, and assisting in the maintenance of overall immune health.
They act as cofactors or coenzymes in various biochemical reactions that are essential for the immune response.
While all vitamins are important for overall health, certain vitamins, such as;
- vitamin C
- vitamin D, and
- the B vitamins
are particularly known for their immune-supporting properties.

Answer:
(a) 300 W
(b)0.90 J
Explanation:
(a) The electric power for any circuit element is given as
Here I is current passing in the circuit and V is the voltage.
Given I = 12 A and V =25 V.
Substitute the given values, we get
P = 300 W.
Thus, the power defibrillator deliver to the body is 300 W.
(b) To calculate the electric energy use the relation between electric energy, power and time as
Given t = 3 ms.
Substitute the values, we get
E = 0.90 J.
Thus, the energy transferred is 0.90 J.
white light from the surface of a mirror
B.
colored light as it travels from a solid medium to a liquid medium
C.
visible light as it passes through a lens
D.
sunlight through droplets of water in the atmosphere
Answers
A). No. A mirror doesn't separate light into its different wavelengths.
B). No. Light doesn't separate into its different wavelengths when it
goes, say, from glass into water.
C). No. When light goes through your glasses, it doesn't separate
into its different wavelengths.
D). Yes ! When sunlight shines into droplets of water in the atmosphere,
it comes out separated into its different wavelengths. When we see that
happening in the air in front of us, we call it a "rainbow".
