Answer:

b) 72 F°

Explanation:

In Fahrenheit, the difference between freezing and boiling is 180 F° (that’s 212 °F minus 32 °F). In Celsius, the difference is 100 C° (by definition of 0 °C and 100 °C for those two points). So 100 C° = 180 F°; dividing by 100 gives us 1 C° = 1.8 F°.

So a difference of 40 C° is equal to 40 times (1.8 F°) = 72 F°.

Notice I am using °F and °C for actual temperatures, and F° and C° for temperature DIFFERENCES.

Mia plays soccer for her high school team. Generally, they start practice by stretching. What kind of stretching should they do before they are warmed up?
A.
ballistic stretching
B.
dynamic stretching
C.
flexibility stretching
D.
static-active stretching

PLEASE NO LINKS

Answers

Answer: Dynamic stretching

Explanation: dynamic stretching is the most ideal way to stretch when warming up becauses it uses the force production of the muscles and momentum during various activities to take the joints through their full, available range of motion, better preparing them for a resistance

The kind of stretching they should do before they are warmed up is dynamic stretching.

What does dynamic stretching mean?

A dynamic stretch is a movement-based type of stretch. It uses the muscle itself to induce stretching. It differs from traditional "static" stretches because the stretch position is not preserved.

Extend your left foot backward, bend your right foot forward and bend it, and rotate left and right to raise your arms to the sky. Or why not stand and add another kind of gentle twist.

Dynamic stretches are based on movement, while static stretches move the joints as much as possible and hold them for a period of time (usually 30-90 seconds).

how Long does it take the car to travel 60m?

Answers

Answer: see below

Explanation:

The intial speed is u=0[tex]\frac{m}{s}[/tex]

The acceleration is a= 3.3[tex]\frac{m}{s}^2[/tex]

The distance is s=60m

Apply the equation of motion

Answers

Hi there!

We can solve this in two ways, using the Work-Energy theorem or kinematics.

Work-Energy:

We know that:

Ei = Ef, as long as there are no external forces working on the system.

Thus:

Ei = PE = mgh

Ef = KE = 1/2mv²

Therefore:

mgh = 1/2mv²

We can cancel out the mass:

gh = 1/2v²

9.8(10) = 1/2v²

√196 = v = 14 m/s

We can also solve using kinematics, using the equation:

vf² = vi² + 2ad

From rest (vi = 0 m/s) and a = g, so:

vf² = 2gd

vf = √2gh

vf = √(2 × 9.8 × 10) = 14 m/s

What is the acceleration of a Ford Mustang GT that can go from 0.00 to 27.8
m/s in 5.15 seconds?

Answers

Finding acceleration= final speed-initial speed/time taken (or A=V-U\T)

Finial speed= 27.8s
Initial speed= 0s

How do X rays use electromagnetic waves to function?

X-rays are very high-frequency waves and carry a lot of energy. They will pass through most substances, making them useful in medicine and industry to see inside things. An X-ray machine works by firing a beam of electrons at a "target." If we fire the electrons with enough energy, X-rays will be produced.

A 0.12 kg object makes an elastic head-on collision with a 0.18 kg stationary object. The final velocity of the 0.12 kg object after the collision is 0.048 m/s in the direction opposite its initial movement. The final velocity of the 0.18 kg object after the collision is 0.19 m/s in the same direction as the object which strikes it. What was the initial velocity of the 0.12 kg object?

Answers

Answer:

0.12kg / 0.19

Explanation:

Becase the volcity reuded

The final velocity of the 0.18 kg object after the collision is 0.19 m/s in the same direction as the object which strikes it, then the initial velocity of the 0.12 kg object would be 0.237 m / s .

What is momentum?

It can be defined as the product of the mass and the speed of the particle, it represents the combined effect of mass and the speed of any particle, and the momentum of any particle is expressed in Kg m/s unit.

As given in the problem, a 0.12 kg object makes an elastic head-on collision with a 0.18 kg stationary object. The final velocity of the 0.12 kg object after the collision is 0.048 m/s in the direction opposite its initial movement. The final velocity of the 0.18 kg object after the collision is 0.19 m/s in the same direction as the object which strikes it.

By using the conservation of the momentum,

v × 0.12 + 0 × 0.18 = ( - 0.048)× 0.12 + 0.19 × 0.18

v = 0.237 m / s

Thus, the initial velocity of the 0.12 kg object would be 0.237 m / s .

If Ms. Ramirez drops a watermelon from the top of the second-floor fire escape outside her room, and it takes 1.5 seconds to hit the ground, calculate the velocity of the watermelon as it hits the ground.

The velocity of the watermelon as it hits the ground is 14.715 m/s.

Given the data in the question;

Since the Watermelon was dropped from rest,

Initial velocity of the Watermelon;[tex]u = 0m/s[/tex]Time taken for the Watermelon to hit the ground; [tex]t = 1.5s[/tex]We know that, Acceleration due to gravity; [tex]g = 9.81 m/s^2[/tex]

Now, we determine the velocity of the watermelon as it hits the ground which is the final velocity.

From the First Equation of Motion:

[tex]v = u + at[/tex]

Now, under gravity, acceleration ''a" will Acceleration due to gravity;[tex]g = 9.81m/s^2[/tex], "v" is the final velocity, "u" is the initial velocity and "t" is the time taken.

So, we substitute our values into the equation

[tex]v = 0m/s\ +\ ( 9.81m/s^2\ * 1.5s )\\\\v = ( 9.81m/s^2\ * 1.5s )\\\\v = 14.715 m/s[/tex]

Therefore, the velocity of the watermelon as it hits the ground is 14.715 m/s

Kinsley stared at her reflection, noting the nose upturned too much, lips too thin, and wondered just how much hair one needed to cover these ears. Clearly, much more than she had, Kinsley reasoned as she glided the comb through her brown tresses. How could her little sister be jealous of this mess? Kinsley sighed too loudly, and her bangs blew out of place and the tip of her ear emerged from her hair. Maybe she should start wearing a hat. Taking her phone, she turned her head and raised her chin, pursing her lips in a vain effort to make them look full, and snapped a selfie. Only seven selfies later, she took one that she deemed "postable" and uploaded it to her social media page. She was getting better at this; the last one took no less than thirteen tries to get all her disagreeable parts to appear inconspicuous enough to satisfy her discriminating eye. These ears were not going to humiliate her, and she was certainly not going to give Megan Pendergrass an opportunity to mortify her again. Meryl banged on the door, and before Kinsley could grant her permission or bar her from entering, she was breaking in and flopping onto her bed. "Are you still staring at yourself? You know, Narcissus died and turned into a flower doing that," Meryl said. "It's really not good to be so in love with yourself," she offered, flipping through Kinsley's teen magazine. If only I did love myself, Kinsley thought, pulling on a pink-and-white checked hat, breaking in the floppy brim until she could make it cover her protruding ears. "Love the Body You're In by Rochelle Rodriguez," Meryl mused. "You certainly don't need to read this article! I'm watching TV if you want to join me." Meryl tossed the magazine, open to the article, on Kinsley's bed and left. Kinsley picked it up and began reading. Thirty minutes later, she removed the hat, positioned the camera and smiled. One ear still peeked through her thin, brown hair, but this was the body she was in, and she would love it.
