Answer:
the initial velocity of the particle is 5 cm/s
Explanation:
Given initial displacement as, s = 6t² + 5t - 5
s is measured in "cm"
t is measured in "seconds"
Velocity is the rate of change of displacement with time. Expressed as follows;

for initial velocity, time (t) = 0
v = 12(0) + 5
v = 5 cm/s
Therefore, the initial velocity of the particle is 5 cm/s
Answer: The correct answer for this question is letter (B) The electromagnetic waves reach Earth, while the mechanical waves do not. The sun generates both mechanical and electromagnetic waves. Space, between the sun and the earth is a nearly vacuum. So mechanical wave can not spread out in the vacuum.
Hope this helps!
Answer:
Volts/Meter
Newtons/Coulomb
Explanation:
Volts/ Meter and Newtons/Coulomb both are same and the units of Electric field intensity or electric field strength.
Electric field strength E is the force per unit charge. It is measured in Newton/Coulomb in SI unit. It is a vector quantity directed in the direction of force.
Mathematically,
Electric field strength = Force/Charge
E = F / q₀
= Newton / Coulomb = NC⁻¹ 1
We know that
Newton = Joule/meter 2
Also
Volt = Joule/Coulomb 3
So put 3 in 2 we get
Newton = (Volt Coulomb)/meter put in 1
E = (Volt Coulomb)/(meter Coulomb)
= Volt / meter
Hence
Newton / Coulomb = Volt / meter
