Answer:

Anything in an experiment that remains unchanged.

Explanation:

An example could be the temperature of the laboratory room. If there is something that has an effect on an experiment that is not variable, it is a constant. Another constant could be, say, if you were doing calculations with the same amount and kind of fluid throughout the experiment, then that fluid would also be a constant.

ValentinkaMS [17]

Answer:

Option B

Explanation:

The reliability of an experiment can be increased by conducting experiment sufficient number of times keeping other things constant. Hence, the 10 p coin needs to be flipped again to measure reliability for more than one times.

Hence, option B is correct

A 900 kg car runs into a 70 kg deer at 28 m/s. If the car transfers all of its momentum to the deer, how fast does the deer go f

Alex

Answer:

Mc = 900 Kg

Uc = 28 ms^-1

Md = 70 Kg

Ud = 0

We want Vd

Vc = Vd

This situation is elastic momentum

$m _{c}u _{c}+ m _{d}u _{d} = m _{c}v _{c} + m _ dv _{d} \\ (900 \times 28) + (70 \times 0) = (900 \times v _{d} ) + (70 \times v _{d}) \\ 25200 = (900 + 70)v _{d} \\ 25200 = 970v _{d} \\ v _{d} = \frac{25200}{970} \\ v _{d} = 26 \: m {s}^{ - 1}$

The James Webb Space Telescope (JWST) is a space observatory developed among 20 countries, is being built and operated jointly by NASA, the European Space Agency and the Canadian Space Agency, to be the scientific successor of Hubble and Spitzer. The JWST will offer an unprecedented resolution and sensitivity, some of its main objectives is observe the formation of the first galaxies of the universe and study the formation and evolution of galaxies. The JWST will allow to observe wavelengths within the so-called near-infrared astronomy, but also the orange and red visible light. The importance of this spectrum range is due to the fact that the infrared light can penetrate dusty regions and reveal what is inside. It will be launched in March 2021, the dimensions of its main mirror are 20,197 m × 14,162 m (66.26 ft × 46.46 ft). The JWST will orbit the sun 1.5 million kilometers away from the Earth
