The correct answer to the question is: A) miles/hour and B) metre/ second.

EXPLANATION:

Before answering this question, first we have to understand speed.

The speed of a body is defined as the rate of distance travelled or the distance travelled by a body per unit time.

Hence, it is a derived quantity which is obtained from distance and time.

The unit of distance can be metre, miles, and the unit of time can be second, minutes or hour.

As speed is the distance covered per unit time, the perfect units will be miles/hour and metre/second.

Hence, the correct options are first and second.

The latin word (Cirro) mean that the clouds are in high level <br><br> True of false?

Ivahew [28]

Answer:

False

Explanation:

The Latin word "Cirro" means "curly" or "curl of hair" as in a cirrocumulus cloud. Cirrocumulus clouds are wispy clouds, and while they do appear high in the sky, the word "cirro" does not mean high in level.

Therefore, the answer is False.

Have a lovely rest of your day/night, and good luck with your assignments! ♡

An archer shoots a 150. gram arrow straight up in the air. (Do not try this at home.) The bow was drawn back 75.0 cm by a 175 N

Dmitry [639]

Answer:

The arrow rise 44.64 m high assuming air friction is negligible

Explanation:

According to the law of conservation of energy

Kinetic energy = Potential energy at highest

$\frac{1}{2}kx^2=mgh$ ----1

We know that F=kx

So, $k = \frac{F}{x}\\k=\frac{175}{0.75}$

Substitute the value in 1

$\frac{1}{2}(\frac{175}{0.75})(0.75)^2=0.15 \times 9.8 \times h\\\frac{\frac{1}{2}(\frac{175}{0.75})(0.75)^2}{0.15 \times 9.8}=h\\44.64 = h$

Hence the arrow rise 44.64 m high assuming air friction is negligible

Condominiums usually require a monthly fee for various services. At $235 a month, how much would a homeowner pay over a period o

Ivahew [28]

Answer:

$28200

Explanation:

Since 1 year has 12 months, 10 years have 120 months.

If one has to pay $235 a month, in 120 months one has to pay $235 done 120 times, which is the product of both numbers:

$P=($235)(120)=$28200$

Which of these is a good example of Newton's First Law of inertia

Eddi Din [679]

Answer: The correct option is A.

Explanation:

Inertia is a state of an object or body to maintain its state. It resists any change in its state.

Newton's first law of inertia: When an objects is in state of motion, it will remain its state of motion or if it is in state of rest then it will remain in rest unless it is acted upon by external motion.

In the given options, a ball sits motionless on the ground is good example of Newton's first law motion. No external force is acting in this case.

In options (B), (C) and (D) , the external force is acting.

Therefore, the correct option is A.
