Answer:
Resultant force = (232.93î + 246.10j) N
x-component of the resultant force = (+232.93î) N
y-component of the resultant force = (+246.1j) N
Explanation:
The net external force on the statue is equal to the resultant force on the statue.
And the resuphant force is a vector sum of all the other forces acting on the statue.
Force 1 = (45î) N
Force 2 = (105j) N
Force 3 = (235cos 36.9°)î + (235 sin 36.9°)j = (187.93î + 141.10j) N
Resultant force = (Force 1) + (Force 2) + (Force 3)
Resultant force = 45î + 105j + (187.93î + 141.10j) = (232.93î + 246.10j) N
Hope this helps!!!
Explanation:
T = 2π √(L / g)
1.0 s = 2π √(L / 19.6 m/s²)
L = 0.50 m
Answer: Conduction- Touch transfer heat and Earth warms air
Convection- liquid/gas transfers heat and warm air rises
Radiation- Sun heats Earth and Waves transfer heat
Explanation:
We get heat on earth from the sun. Energy from the sun is transferred through space and through earths atmosphere to the earths surface. And since this warms the earth surface it creates heat.
Answer: 150000 g
Explanation:
Firstly, we need to calculate the volume of the tank :
(1)
Now, is the volume that has to be filled with water, this means the volume water occupies in the tank must be equal to the volume of the tank:
(2)
On the other hand, the density of water is and establishes the relation between its mass and its volume :
(3)
Clearing :
(4)
(5)
Finally:
