One advantage of the hubble space telescope over ground based ones is that

vladimir1956 [14]

Space telescopes have the advantage of being above the blurring effects of the Earth's atmosphere.

A surrounding is a layer of fuel or layers of gases that envelop a planet and is held in a region through the gravity of the planetary frame. A planet retains its surroundings whilst the gravity is exceptional and the temperature of the surroundings is low. A stellar ecosystem is the outer area of a celeb, which includes the layers above the opaque photosphere; stars of low temperature may have outer atmospheres containing compound molecules.

The atmosphere of Earth consists of nitrogen (78%), oxygen (21%), argon (0.9%), carbon dioxide (0.04%), and trace gases. most organisms use oxygen for breathing; lightning and bacteria perform nitrogen fixation to provide ammonia that is used to make nucleotides and amino acids; flora, algae, and cyanobacteria use carbon dioxide for photosynthesis.

The layered composition of the ecosystem minimizes the damaging results of daylight, ultraviolet radiation, solar wind, and cosmic rays to defend organisms from genetic harm. The modern composition of the atmosphere of the Earth is made from billions of years of biochemical modification of the paleo atmosphere by residing organisms.

If you are driving 80 km/h along a straight road and you look to the side for 2.1 s , how far do you travel during this inattent

ella [17]

Velocity = displacement / time

First, Always make sure that your units for things are the same. In this question, we are given time in seconds and hours. So, we need to make them all use 1 unit.

I will do seconds.

To convert 80km/h to m/s, divide by 3.6.

22.2222…. m/s = displacement / 2.1s

Multiply by 2.1s on both sides

46.6666……m = displacement

You travelled 47 meters.

Give your answer with solution(Easy Question)

Furkat [3]

Volume of any rectangular prism is (length) x (width) x (height).

The box in the picture is definitely a rectangular prism, so its volume is

(length) x (width) x (height) .

That's (4.0 cm) x (6.0 cm) x (2.0 cm) = 48 cm³ .

So the volume of the box is 48 cm³ fer sher, but that's NOT the preferred answer to this question. If you take your time and read all the fine print carefully, you'll see that this sneaky question wants the answer in units of meter³ . In order to produce the answer that it's fishing for, YOU have to be sneaky too. You have to convert units, either before you start doing the calculating, or else convert the units of your result before you choose the answer from the list.

Before you calculate: Convert the given dimensions to (meters). Then

Volume = (0.04 m) x (0.06 m) x (0.02 m)

Volume = 0.000048 m³

Volume = 4.8 x 10⁻⁵ m³

After calculating but before picking the answer:

Volume = (4.0 cm) x (6.0 cm) x (2.0 cm)

Volume = (48 cm³)

Convert:

Volume = (48 cm³) x (1 meter / 100 cm)³

Volume = (48 cm³) x (1 meter³ / 10⁶ cm³)

Volume = (48 cm³ meter³ / 10⁶ cm³)

Volume = 48 x 10⁻⁶ m³

or

Volume = 4.8 x 10⁻⁵ m³

This is exactly the same number as 48 cm³, but this is the way they want to see it, and 48 cm³ isn't. So you have to select choice - D .

A motor is connected to the smaller 0.2 m radius pulley and cable, lifting 150 kg mass. Neglecting the mass/weight of the cable

-Dominant- [34]

Answer:

324.3Nm

Explanation:

The torque is given by the equation

$\tau=r\ X\ F$

in this case the vectors r and F are perpendicular between them, thus:

$\tau=rF$

The forces acting on the mass are:

$T-Mg=Ma$ (1)

where T is the tension of the cable, M is the mass and a is the acceleration.

Furthermore, we have that the acceleration is:

$a=\frac{v-v_0}{t}=\frac{10m/s-0m/s}{10s}=1\frac{m}{s^2}$

By replacing in (1) we can obtain:

$T=Ma-Mg=M(a-g)=(150kg)(1\frac{m}{s^2}+9.8\fac{m}{s^2})=1620N$

The force T produces the torque on the pulley, hence:

$\tau=rT=(0.2m)(1620N)=324Nm$

the answer is 324.4Nm

hope this helps!
