Answer:
B
Explanation:
Let m be mass of the object and v be speed of object b.
Kinetic Energy of B = 1/2 mv^2
Kinetic Energy of A = 1/2 m(2v)^2
= 2 mv^2
= 4 (1/2 mv^2)
= 4 × Kinetic Energy of B
Hence Object A has four times the kinetic energy of object B (<em>A</em><em>n</em><em>s</em><em> </em><em>B</em><em>)</em>
Answer:
<u>The factors affecting climate are latitude, altitude, land and water distribution, distance from the sea, distance from the sun, prevailing winds and ocean currents, surface covering the land, volcanism, solar constant sunspots, wind direction and nature of mountain chains, mountain barriers.</u>
Answer:
infinity
Explanation:
Given that
Resistance = R
Resistivity = ρ
Length = L
Diameter = d
The resistance of wire R given as

A=Area

Now by putting the value of A


When d tends to infinity then d² will also tends to infinity.
So when d tends to zero then the resistance tends to infinity.
Therefore answer is ---
infinity
Answer:
The photoelectric effect is a phenomenon in which the photoelectrons are emitted from the metal when an incident electromagnetic wave hits the metal. The incident light should have a threshold frequency to meet the work function of the metal
