It is dangerous for children. Air bags are dangerous to children age 12 and under because the bag inflates at speeds up to 200 mph and that sudden blast of energy can severely injure or kill passengers who are too close to the air bag. If possible, children should ride in the center of back seat, properly restrained with a seat belt.
Answer:
W = 0
Explanation:
We are given with, a construction worker is carrying a load of 40 kg over his head and is walking at a constant velocity. He travels a distance of 50 m.
The work done by an object is given by :

F = ma
So,

m is mass
a is acceleration
d is displacement
The worker is moving with constant velocity, its acceleration will be 0. So, the work done by the worker is 0.
A material that can easily flow is called a...
A. Fluid.
C) refract
Explanation:
When light passes from air into water, the light waves will bend or they refract and the pencil will appear to be broken.
In normal space, light travels along a straight path with no alteration of the path along which it travels.
- When light crosses the boundary from a denser to a less dense medium, it is refracted.
- Refraction implies that the angle of the light is bent.
- This is because the new medium causes the light rays to slow down compared to the speed it was coming forth with.
