jawaban: what is languange?

Answer:

Option B

Explanation:

The muscles around your heart consist of "cardiac muscles" or option B. Cardiac itself means heart or involving the heart, and cardiac muscles is one of the main components or tissue that surrounds your heart. It's not option A because skeletal muscles are the muscles that cover your bones, it's not option C because smooth muscles are only involved with digestion and gaining nutrients for your body. Which leaves option D and strong muscles isn't the answer because strong muscles is the amount of force a person can put out or strength.

Hope this helps.

Explanation:

v² = u² + 2as

v² = 17² + 2(-9.8)(-51)

v² = 1,288.6

v = ±35.89707...

v = 36 m/s

Answer:

1. What is the force of friction between a block of ice that

weighs 930 N and the ground if m = .12?

F fr £ µ sF N

F fr = µ kF N

F = ma

F N = 930 N

µ s = .12

F fr =µ kF N = (930)(.12) = 111.6 N = 110 N

(Table of contents)

2. What is the coefficient of static friction if it takes 34 N of

force to move a box that weighs 67 N?

F N = 67 N

µ s = ?

F fr =34 N

F fr = µ kF N

34 = µ k(67)

µ s = .507 = .51

(Table of contents)

3. A box takes 350 N to start moving when the coefficient of

static friction is .35. What is the weight of the box?

F N = ?????

µ s = .35

F fr =350 N

F fr = µ kF N

350 = (.35)F N

F N = 1000 N = 1.0 x 10 3 N

4. A car has a mass of 1020 Kg and has a coefficient of

friction between the ground and its tires of .85. What force of

friction can it exert on the ground? What is the maximum

acceleration of this car? In what minimum distance could it

stop from 27 m/s?

First find the normal force which is the weight in this

case:

F = ma = (1020 kg)(9.80 m/s/s) = 9996 N = F N

Then use the Friction formula to find the frictional

force with the ground:

F fr = = (.85)(9996 N) = 8496.6 N = 8500 N

Now we can find the acceleration. The Force of

friction is what speeds up the car, so

F = ma

8496.6 N = (1020 kg)(a)

a = 8.33 m/s/s = 8.3 m/s/s

So now we need to solve a cute linear kinematics

problem:

x = ?????

v i = 27

v f = 0

a = -8.33 m/s/s (slowing down)

t = don't care

Use vf 2 = vi 2 + 2ax:

0 2 = (27) 2 + 2(-8.33 m/s/s)s

x = 43.76 m = 44 m

5. Clarice moves a 800. gram set of weights by applying a

force of 1.2 N. What is the coefficient of friction?

m = 800. g = .800 kg (divide by 1000)

First find the normal force which is the weight in this

case:

F = ma = (.800 kg)(9.80 m/s/s) = 7.84 N = F N

Next - apply the force of friction formula:

F fr = µ kF N

1.2 N = µk (7.84 N)

µ k = .15306 = .15

(Table of contents)

Explanation:

Note that is not an answer that is guide

thanks po

hope it help ❤️

Answer:

In order to calculate the value of force without radius, you may need the circumference whose formula is C=2πr. You can also find this force by calculating just acceleration using the formula: And this is also called Newton’s second law of motion, which can be calculated by entering acceleration and mass of the object.

Answer:

Participate in beach cleanups to reduce water pollution.

Explanation:

Answer:

Vy = 18 sin 32 = 18 * .5 = 9.54    vertical speed

Vx = 18 cos 32 = 18 * .848 = 15.3 m/s horizontal speed

ty = Vy / 9.80 = .973 to get to top

t = 2 ty = 1.95 sec  (total time in air

Average speed up = 9.54 / 2 = 4.77 sec

Height ball rises = 4.77 * .973 = 4.64 m

Or H = Vy t - 1/2 g t^2

H = 9.54 * .973 - 4.9 * .973^2 = 4.64 m   as found above

D = Vx t = 15.3 *  1.95 = 29.8 m       for distance traveled

Hi there!

The Amplitude is the 'A' value of the following SHM equation:

[tex]x(t) = Asin(\omega t)[/tex]

Thus, the amplitude of this object:

A = 0.50 m

The period of vibration is equivalent to:

[tex]T = \frac{2\pi}{\omega}[/tex]

In this instance:

[tex]\omega = \frac{\pi}{2}[/tex]

Therefore:

[tex]T = \frac{2\pi}{\frac{\pi}{2}} = \frac{4\pi}{\pi} = \boxed{\text{ 4 seconds.}}[/tex]

Answer:

There is pressure on both the in and outsides of the balloon: high inside and low outside, respectively. In terms of air mass, high pressure has greater activity and tends to move upward (balloon rises); whereas low presssure, being slower, descends (balloon descends).
