Answer:
Net force = 7.10 N
Direction of the resultant force = 45° from the horizontal in South-west direction
Explanation:
Forces acting on opposite directions horizontally are 10N and 5N.
Resultant force horizontally F(1) = 10 - 5 = 5N (in the direction of 10 N)
Forces acting on opposite directions vertically are 7N and 2N.
Resultant force vertically F(2) = 7 - 2 = 5N (in the direction of 7N)
Now resultant force of F(1) and F(2),
F =
F =
F = ≈ 7.10 N
From the triangle OBC,
tanθ =
tanθ =
θ = 45°
Therefore, magnitude of the resultant force = 7.10N
Direction of the resultant force = 45° from the horizontal in south west direction.
Potential Energy= 24m * 14kg * 9.8N/kg = 3292.8J
The answer is C. gravity.
Answer:
Tension= 475N
Force= 225N

The question is not complete, here is the complete question
Also, see attached a free body diagram for your reference
<em>"A 20.0-kg uniform plank is supported by the floor at one end by a vertical rope at the other as shown in the figure. A 50.0-kg mass person stands on the plank a distance three-fourths of the length plank from the end on the floor.
</em>
<em>a. What is the tension in the rope?
</em>
<em>b. What is the magnitude of the force that the floor exerts on the plank?"</em>
<em />
given data
mass of man=50kg
mass of plank=20kg
length of plank=10m
<em />
let us make the lenght of the rope be d
The torque about the floor
That is taking moment about the floor
Force will be also zero

Answer:
TRUE
Explanation:
BECAUSE AN OBJECTS DENSITY SHOWS HOW MUCH WEIGHT IS PER CUBIC UNIT. LIKE SAD HAS MORE DENSITY THAN WATER SO IT SINKS WHILE WOOD HAS LESS DENSITY THAN WATER SO IT FLOATS
