Answer:
10N right
Explanation:
First, we need to find the base of the triangle to find the force acting on the right of the object.
- We have been given the hypotenuse and we need to find the adjacent, so we are using cos
- SOH, CAH, TOA
- cos(θ) = adjacent ÷ hypotenuse
Next, sub in the values (we don't know the adjacent so i've called it x):
To find x, we need to multiply both sides by 60
Now we know all the forces, we can work out the net force:
- Both of the 40N cancel out because they are opposite forces
- The force on the right of the object is 10N stronger than the force on the left (30N - 20N), so the object would move to the right
Answer:
Linear mass density,
Explanation:
Given that,
Mass of the string, m = 0.3 g = 0.0003 kg
Length of the string, l = 1.5 m
The linear mass density of a string is defined as the mass of the string per unit length. Mathematically, it is given by :
or
So, the linear mass density of a string is 
. Hence, this is the required solution.
four seasons, each lasting for about 21 earth years
summer has sun the entire time, while the winter is in full darkness
spring and autumn have a day night cycle
