Answer:
1398.12 N
Explanation:
We define the x-axis in the direction parallel to the movement of the truck on and the y-axis in the direction perpendicular to it.
x-components of the ropes forces
T₁x = 615N*cos31°=527.1579 N :Tension in direction x of the rope of the car 1
T₂x= 961 N*cos25°=870.96 N :Tension in direction x of the rope of the car 2
Net forward force exerted on the truck in the direction it is headed (Fnx)
Fnx = T₁x + T₂x
Fnx = 527.1579 N + 870.96 N
Fnx = 1398.12 N
Answer:
Acceleration (b) not sure tho
Explanation:
Answer:
v = 18.84 m/s
Explanation:
Let the question says,"The blade of a 0.30 m diameter fan rotates 1200 rev / min. calculate the tangential speed."
It is given that,
Diameter of a blade of fan is 0.3 m
Angular velocity of the fan is 1200 rev/min or 125.66 rad/s
We need to find the tangential speed of the fan. The relation is given by :
r is radius of fan
So, the tangential velocity is 18.84 m/s.
Answer:
5 solar days is 432,000 seconds
Explanation:
One solar day is the time the meridian of the Sun crosses passes through a specified place.
Due to the elliptical orbit of the Earth round the Sun, one average solar day on Earth is equivalent to 24 hours with some days longer and some days shorter each by a few minutes
Therefore, we have;
5 solar days = 5 × 24 hours × 60 minutes/hour × 60 seconds/minute = 432,000 seconds
5 solar days = 432,000 seconds
