Answer:

the only way to burn calories is to burn more calories than you consume

fat is very unhealthy to the body, and can cause serious issues

if you do not burn calories, they will turn into fat

The __________muscle raises the eyebrows and causes wrinkles across the forehead.

sweet [91]

Horizontal forehead wrinkles are caused by contraction of the frontalis muscles. The frontalis muscles are two large fanlike muscles that extend from the eyebrow region to the top of the forehead. I think this is the answer

A rocket with a mass of 62,000 kg (including fuel) is burning fuel at the rate of 150 kg/s and the speed of the exhaust gases is

mezya [45]

Answer:

h≅ 58 m

Explanation:

GIVEN:

mass of rocket M= 62,000 kg

fuel consumption rate = 150 kg/s

velocity of exhaust gases v= 6000 m/s

Now thrust = rate of fuel consumption×velocity of exhaust gases

=6000 × 150 = 900000 N

now to need calculate time t = amount of fuel consumed÷ rate

= 744/150= 4.96 sec

applying newton's law

M×a= thrust - Mg

62000 a=900000- 62000×9.8

acceleration a= 4.71 m/s^2

its height after 744 kg of its total fuel load has been consumed

$h= \frac{1}{2}at^2$

$h= \frac{1}{2}4.71\times4.96^2$

h= 58.012 m

h≅ 58 m

A wire of length 26.0 cm carrying a current of 5.77 mA is to be formed into a circular coil and placed in a uniform magnetic fie

Olin [163]

Answer:

The maximum torque is $\tau_{max} = 1.139 *10^{-7} \ N \cdot m$

Explanation:

From the question we are told that

The length of the wire is $l = 26.0 \ cm = 0.26 \ m$

The current flowing through the wire is $I = 5.77mA = 5.77 *10^{-3} \ A$

The magnetic field is $B = 3.67 \ mT = 3.67 *10^{-3 } T$

The maximum torque is mathematically evaluated as

$\tau_{max} = \mu B$

Where $\mu$ is the magnetic dipole moment which is mathematically represented as

$\mu = \frac{I l^2}{4 \pi n }$

Where $n$ is the number of turns which from the question is 1

substituting values

$\mu = \frac{ 5.77 *10^{-3} * 0.26^2}{4 * 3.142* 1 }$

$\mu = 3.10 4* 10^{-5} A m^2$

Now

$\tau_{max} = 3.104 *10^{-5} * 3.67 *10^{-3}$

$\tau_{max} = 1.139 *10^{-7} \ N \cdot m$

Which of the following occurs first in the generation of an action potential?

spayn [35]

It seems that you have missed the necessary options for us to answer this question so I had to look for it. Anyway, here is the answer. The one that occurs first in the generation of an action potential is that t<span>he membrane depolarizes. Hope this answers your question. Have a great day!</span>
