Answer:
The electric field is
Explanation:
The force
on a charge
in an electric field
is given by
,
which can be rearranged to give

Now, the force on the electron is
, and its charge is
; therefore,


Answer:
A
Explanation:
T-G-T is the answer .
the matching Nitrogen base sequence for gene ATC is A
The answer is A........The sound is transferred by collisions of molecules. Therefore sound waves will travel faster on warm air because collisions of molecules of air in warm air are greater.
Answer
given,
Mass of the runner, M = 70 Kg
speed of the runner on the second base = 4.35 m/s
speed at the base = 0 m/s
Acceleration due to gravity,g = 9.8 m/s²
a) magnitude of mechanical energy lost
Mechanical energy lost is equal top gain in kinetic energy



b) Work done = Force x displacement
W = F. x
F = μ mg
W = μ mg . x
Work done is equal to 662.29 J

using the coefficient of the friction,μ = 0.7

x = 1.38 m
Hence, the runner will slide to 1.38 m.
