Answer:
3.91
Explanation:
Given that
Final reading of the voltmeter, V2 = 45 v
Initial reading of the voltmeter, V1 = 11.5 v
The dielectric constant k, of a material is usually given as
k = V2/V1
k = 45 / 11.5
k = 3.91
Therefore, the dielectric constant of the material as we've calculated above is sure to be 3.91.
I hope that helps you understand
In projectile motion we can say initial components of velocity is
now here horizontal motion is uniform motion as there is no force in this direction while in vertical direction due to gravity it will accelerate
so we have
so here we have x and y coordinates are related to each other as it will take same time to move the positions
so here correct options are
<em>Projectile motion is a combination of horizontal and vertical motion.
</em>
<em>The horizontal and vertical motions of a projectile are dependent on each other.</em>
V = p / m
V = 1000 / 2.5
V = 400 m/s
hope this helps!
1) Vacuum tube
2) silicon
3) integrated, I.C.s
4) this one is worded weird. Transistors are the main part of voltage regulators but they use (require) diodes and capacitors, too. And they are all put onto a microchip in the power distribution section. sorry for the long explanation.
5) away from
6) directly, inversely
According to Newton's second law of motion, acceleration of the object is directly proportional to the net force in the object. It is expressed as:
F = ma
where F is the net force, m is the mass of the object and a is the acceleration.
20N = 5/1000 kg (a)
a = 4000 m/s²
