Answer:
42 m
Explanation:
= initial velocity of the car = 24 m/s
= final velocity of the car = 0 m/s
μ = coefficient of kinetic friction = 0.7
g = acceleration due to gravity = 9.8 m/s²
a = acceleration due to kinetic frictional force = - μg = - (0.7)(9.8) = - 6.86 m/s²
d = distance through which the car skids
Using the kinematics equation
Inserting the values
d = 42 m
Answer: voltage (V)
Explanation:
Hi, in the answer the letter A (1.2 A) stands for Ampere, and the symbol next to the number 24 must be Ω 8 (Ohms)
So, applying Ohm's law:
Voltage (V) =current (I) x resistance (R)
V = I x R
Replacing with the values given;
V = 1.2 A x 24Ω
In conclusion, we can calculate the value of Voltage for the circuit.

Answer:
"we both attract each other with the same force but we know that attraction between two bodies depends upon their mass, greater the mass of two bodies is the force of attraction between them"(got this off the internet).
Carbon dioxide is the most abundant greenhouse gas in the atmosphere.
Given that,
The electric field is given by,
Suppose, B is the amplitude of magnetic field vector.
We need to find the complete expression for the magnetic field vector of the wave
Using formula of magnetic field
Direction of 
vector is the direction of propagation of the wave .
Direction of magnetic field = 
We need to calculate the poynting vector
Using formula of poynting
Put the value into the formula
Hence, The poynting vector is
