Answer:
(a). The resultant of these forces is 1216.55 N.
(b). The direction of the resultant forces is 80.53°.
Explanation:
Given that,
First force = 1200 N
Second force = 200 N
(a). We need to calculate the resultant of these forces
Using cosine law
Put the value into the formula
The resultant of these forces is 1216.55 N.
(b). We need to calculate the direction of the resultant forces
Using formula of direction
Put the value into the formula
Hence, (a). The resultant of these forces is 1216.55 N.
(b). The direction of the resultant forces is 80.53°.
Answer:
Wavelength,
Explanation:
In an electromagnetic wave both electric and magnetic field propagate simultaneously. Radio waves, microwaves, gamma rays etc are some of the examples of electromagnetic waves.
If f is the frequency of electromagnetic wave, c is the speed of light, then the relationship between the frequency f, wavelength and the speed is given by :
Hence, the correct option that shows the wavelength of electromagnetic wave in free space is(a) " c/f ".
Answer:
Velocity become 5 m/s south,
I didnt get from second line.....
Answer:
Then its acceleration is zero.
Explanation:
Velocity → Uniform → Constant
→ Change in Velocity = 0
A= = (v=m)
a=0
