Answer:
6.78 km
Explanation:
Length of path due east = 4.3km
Length of path south = 2.48km
Unknown:
Distance covered = ?
Solution:
The distance covered is the total length of path from start to finish. It takes cognizance of the turns and every direction moved.
Unlike displacement which only considers the net direction from start to finish, distance sums up the total path.
So;
Distance = 4.3km + 2.48km = 6.78km
The conservation of energy equation?
K1 + U1 = K2 + U2
Or the Kinetic energy equation?
KE = 1/2 mv²
Gravitational potential energy?
Ug = mgΔy
Elastic potential energy?
Ue = 1/2 kx²
Answer:
Explanation:
The problem is based on resolving power of instruments . Resolving power of instruments is related to wavelength of light as follows
resolving power of telescope ∝ 1 / λ
Higher the resolving power closer the object that can be looked separately.
Wave length of blue light is shorter than that of red light so resolving power in case of blue light will be higher. So we have better chance of distinguishing separate bulbs when color light is blue.
