In Space, an astronaut releases a wrench from his hand. The wrench has a mass of 4 grams and is traveling with a velocity of -15

Vladimir [108]

Answer:

$v_2=8.85\times 10^{-4}\ m/s$

Explanation:

We have,

Mass of a wrench, m₁ = 4 g = 0.004 kg

Speed of wrench, v₁ = -15 m/s

Mass of the Astronaut, m₂ = 70 kg

It is required to find Astronaut's velocity. Let it is v₂. Using the conservation of linear momentum to find it.

$m_1v_1=m_2v_2\\\\v_2=\dfrac{m_1v_1}{m_2}\\\\=\dfrac{0.004\times (-15)}{70}\\\\=-8.85\times 10^{-4}\ m/s$

So, his velocity is $8.85\times 10^{-4}\ m/s$ .

If a wave had a wave speed of 1000 m/s and a frequency of 500 Hz, what is its wavelength?

Reil [10]

Answer:

<h2>2 meters</h2>

Explanation:

<h2>Wavelength = Speed/Frequency </h2><h2>1000 m/s ÷ 500 hz </h2><h2>2 m</h2><h2>hz = s</h2><h2>Hopes this helps. Mark as brainlest plz!</h2>

Assume that the total cholesterol levels for adults are normally distributed with mean cholesterol level of 51.6 mg/dL and stan

Ivahew [28]

Answer:

therefore, the probability that an individual will have a cholesterol level greater than 60 mg/dL.= 0.27

Explanation:

given data

Normal distribution

mean cholesterol level μ= 51.6 mg/dL

Standard deviation σ= 14.3 mg/dL

x= 60 mg/dL

We have to find out P(x>60)

We Know that $P(x>a) =P(Z>(a-\mu)/\sigma)$

therefore, $P(x>60) =P(Z>(60-51.3)/14.3)$

= P(Z>0.61)

= 1 - P(Z<0.61)

= 1 - 0.7291

= 0.27

therefore, the probability that an individual will have a cholesterol level greater than 60 mg/dL.= 0.27

An object travels with velocity v = 4.0 meters/second and it makes an angle of 60.0° with the positive direction of the y-axis.

Galina-37 [17]

Vx=cos60(4)
x-component of velocity
If you think about it, it makes a right triangle when you combine all the different types of forces together such as v, vx and vy. Then, you can use trigonometry and soh cah toa in order to figure out vx.
