Please be more specific because they all transmit signals but the most common one is the radio wave because it transmits cellphone , televition and radio signals
Yes I can do you want me to
The answer is <span>C. 49 m/s
The kinetic equation is:
v2 = v1 + a * t
v1 - initial velocity
v2 - final velocity
a - gravitational acceleration
t - time
We know:
v2 = ?
v1 = 0 (in free fall
a = 9.8 m/s
t = 5
</span>v2 = v1 + a * t
v2 = 0 + 9.8 * 5
v2 = 0 + 49
v2 = 49 m/s
Answer:
Explanation:
Required
The units of A and B
From the question, we understand that:
This implies that each of 
and 
will have the same unit as 
So, we have:
The unit of t is (s); So, the expression becomes
Divide both sides by 
Gravitational potential energy can be given by the equation
PE = mgh
where m is the mass,
g is the gravitational constant 9.81 or 10 depending on rounding
and h is the height
well weight is a force equiavlent to
W= m*g
so comparing that to the potential energy equation, divide the potential energy by the height and you will get weight in Newtons
