A major obstacle to developing a good human relations skill is that : few person have a common interest a communication between two people will be a lot easier if they have common interest because a person tend to like other person that are similar to him (whether it's race, background , or common interest).
Answer:
F = 1480.77N
Explanation:
In order to calculate the required force to push the container with a constant velocity, you take into account the the sum of force on the container is equal to zero. Furthermore, you have for an incline the following sum of forces:
(1)
F: required force = ?
W: weight of the container = 1800N
N: normal force = weigth
α: angle of the incline = 28°
g: gravitational acceleration = 9.8m/s^2
μ: coefficient of friction = 0.4
You solve the equation (1) for F and replace the values of the other parameters:

The required force to push the container for the incline with a constant velocity is 1480.77N
Answer
given,
wavelength (λ) = 650 nm
angle = 5°
using bragg's law



d = 7.46 x 10⁻⁴ cm
number of slits per centimeter
= 
b) wavelength of two rays 650 nm and 420 nm

d = 2 x 10⁻6 m
we now,

for 650 nm


θ = 40.54°
for 450 nm


θ = 24.83°
now, difference
|θ_{650} -θ_{420}| =40.54°-24.83°
|θ_{650} -θ_{420}| =19.71°
Answer:
Food mixer will convert electrical energy into kinetic energy
Explanation:
Energy conservation means that energy can not be created nor destroyed it can be converted from one form into another
Voltage =Current * Resistance
= 9 * 43
Voltage = 387 V
