Answer:
(B) The balls reach the ground at the same instant.
Explanation:
Since it is a projectile motion, the time required to reach the ground is given by
t = √2h/g
Where h is the height from which the balls are thrown and g is the acceleration due to gravity.
Since both of the balls were thrown from the same height and the acceleration of both balls are also same they will reach the ground at the same instant.
Answer:
θ = 56.09°
Explanation:
Given that
h = 8.5 ft
speed ,u= 28 ft/s
We know that acceleration due to gravity g
g= 32.2 ft/s²
The maximum height h is given as
Now by putting the values
θ = 56.09°
Therefore the angle will be θ = 56.09°
It's not. It's equivalent to the transfer of that many elementary charges <u>every second</u> .
The elementary charge (charge on an electron) is
1.60 x 10⁻¹⁹ coulomb / electron.
The number of electrons in a Coulomb is the reciprocal of that number.
6.25 x 10⁻¹⁸ electrons / Coulomb.
There's the number. 1 Coulomb <em>per second</em> is called 1 Ampere.
Answer:
Ampere
Explanation:
The ampere is the unit of measurement in the international system. Its equal to a coulomb/second. It can be describe as the rate of charges flowing throught a conductor
