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 (1 km = 1000 m). Therefore, this matching is not correct.

D. Temperature: in the SI system, temperature is measured in Kelving (K), so this matching is correct.

What happens to a gas that is enclosed in a rigid container when the temperature of the gas is increased?
kiruha [24]
A. the gas particles move faster and collide more frequently, which causes an increase in pressure.

Increasing temperature increases the energy of the gas, which causes the kinetic energy of the molecules to increase.

A car accelerates at a rate of 13m/s^2[S]. If the car's initial velocity is 120km/h[N]. What will be its final velocity in m/s,
balu736 [363]

Answer:

the final velocity of the car is 59.33 m/s [N]

Explanation:

Given;

acceleration of the car, a = 13 m/s²

initial velocity of the car, u = 120 km/h = 33.33 m/s

duration of the car motion, t = 2 s

The final velocity of the car in the same direction is calculated as follows;

v = u + at

where;

v is the final velocity of the car

v = 33.33 + 13 x 2

v = 59.33 m/s [N]

Therefore, the final velocity of the car is 59.33 m/s [N]

Which is an example of a covalent bond?
velikii [3]
The correct answer is definitely C. There are less than 16 valence electrons in 2 chlorine atoms, but they form a stable bond because a covalent bond should involve <span>a pair of electrons between atoms in a molecule. I thing it's pretty clear. Regards!</span>

What is the difference between a hurricane and a typhoon
Lera25 [3.4K]

Answer:

The answer is below

Explanation:

Well, a hurricane is a storm with violent winds (more less with a force of 12 in the scale that measures winds) and it happens especially in the Caribbean sea. While a typhoon is also a strong storm but it happens especially in the Indian region and the western pacific oceans.

In conclusion, their difference is the area in which they happen.
