Answer:
a) 5.5×10^17 Hz
b) visible light
Explanation:
Since the wavelength of the electromagnetic radiation must be about the size of the about itself, this implies that;
λ= 5.5 × 10^-10 m
Since;
c= λ f and c= 3×10^8 ms-1
f= c/λ
f= 3×10^8/5.5 × 10^-10
f= 5.5×10^17 Hz
The electromagnetic wave is visible light
No because your opinion and beliefs answers many questions
D. A solution because it dissolves when mixed with water
Answer:
The Answer is B because the material the object is made of, the position, or the color have absolutely nothing to do with gravitational potential energy
Answer:
The force is 
Explanation:
Given that,
Mass of car = 64 kg
Suppose, a 1400-kg car that stops from 34 km/h on a distance of 1.7 cm.
We need to calculate the acceleration
Using formula of acceleration

Where, v = final velocity
u = initial velocity
a = acceleration
s = distance
Put the value into the formula



We need to calculate the force
Using formula of force



Negative sign shows the direction of the force is in the direction opposite to the initial velocity.
Hence, The force is
