The weight of the block is (mass x gravity) = (50kg x 9.8 m/s²) = 490 N
The NET vertical force on the block is (490N down) + (600N up) = 110N up.
Acceleration = (net force) / (mass)
Acceleration = (110N up) / (50 kg)
<em>Acceleration = 2.2 m/s² up</em>
Answer: Such objects are closer than they look.
Explanation:
Image formed by convex mirror are relatively virtual, smaller than the image and upright, because it forms behind the mirror. Thank you.
Answer:
xxxx
Explanation:
Mars also has a thin atmosphere. Because of this it has potential to host humans and other organic life. That makes Mars the best choice for thriving colony off the earth. The moon has also been proposed as the first location for human colonization but it not known to have air or water.

The sound produced is called wheezing. It is somewhat like a whistle except it's more course and you don't do it voluntarily like whistling, but rather it occurs because of obstructions. It can be either vocally or you can hear it when there are nasal obstructions when you are breathing through your nose.

Answer:
4m/s^2
Explanation:
mass(m)=20 kg
force=80 N
acceleration (a)=?
Therefore,
Force = mass * acceleration
80 = 20*a
a=80/20
=4m/s^2
