Metaphase; the centromeres of duplicated chromosomes line up in the middle of the cell. (It's also the shortest phase of mitosis).
Explanation:
Speed has only magnitude.
Velocity has magnitude and direction.
"A bike goes 25 m/s toward main street."
This includes a direction, so it is velocity (V).
"A person walks 4 mph."
This has only magnitude, so it is speed (S).
"A plane flies 200 m/s."
This has only magnitude, so it is speed (S).
"A bird flies 100 mph due south."
This includes a direction, so it is velocity (V).
Answer:
The velocity at the nozzle at inlet 
= 3584 
Explanation:
Pressure at inlet 
= 1 × 
Pa
Temperature at inlet 
= 518 ° c = 791 K
Mass flow rate = 
= 88.7
Gas constant for carbon die oxide is R = 189 
Mass flow rate inside the nozzle is given by the formula = 
× 
×
⇒ = = 1 × Pa
⇒ R = 791 × 189 = 149499 
⇒ = 0.0037 
Put all the above values in above formula we get,
⇒ 88.7 = 
× 0.0037 ×
⇒ = 3584
This is the velocity at the nozzle at inlet.
Halogens therefore react most vigorously with Group 1 and Group 2 metals of all main group elements.
Answer:
3 x 10^5 J
Explanation:
mass of substance, m = 1 g = 0.001 kg
Velocity of light, c = 3 x 10^8 m/s
According to the Einstein mass energy equivalence, the energy associated with the mass is given by
E = m c^2
E = 0.001 x 3 x 10^8
E = 3 x 10^5 J
