Answer and Explanation:
Before turning a hot plate on, one should consider these points:
- Check for the leads and ensure they does not trail in liquid.
- The cable should be checked for any exposed wire before turning on in order to prevent any shock.
- Any oil residue should be wiped off of the hot plate to ensure its longevity.
- It should be placed in a stable place in order to ensure safety against any hazard.
- Thus all the above mentioned points are correct to ensure safety.
Answer:
In chemistry and physics, a valence electron is an outer shell electron with an atom, and that can participate in the formation of a chemical bond if the outer shell is not closed; in a single covalent bond, both atoms in the bond contribute one valence electron in order to form a shared pair.
Explanation:
Answer:
v = 30.39 m/s
Explanation:
given,
mass of glider,M = 680 Kg
mass of the skydiver, m = 68 Kg
horizontal velocity,V = 30 m/s
when skydiver releases, velocity,v = 30 m/s
velocity if the glider,v' = ?
use the conservation of momentum
M V = m' v' + m v
m' = 680-68 = 612 Kg
680 x 30 = 612 x v + 60 x 30
612 v = 18600
v = 30.39 m/s
since the skydiver's speed will be the same as before release
The glider should continue to travel at 30.39 m/s since there are no external forces acting on it
Answer:
When white light passes through the prism ,different colours suffers deviation through different angles and light appears to be dispersed. But in a hollow prism dispersion does not take place as all the colours travel with same speed in the air inside hollow prism. Thus no angular dispersion is there.
Well you didn’t give answer choices but this sounds like... he’s stereotyping? Stereotypes... ageism....
