Answer:
a) in uniform motion
Explanation:
When velocity-time graph is parallel to x-axis, it shows that the object is moving with constant velocity. or we can say that that the object is moving with uniform motion. There is no change in velocity. It covere equal distance in equal intervals of time.
Hence, the correct option is (a) "in uniform motion".
It equals 23.89.
Hope this helps!!
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:
What constant velocity means
Explanation:
To have a constant velocity, an object must have a constant speed in a constant direction
For Pascal's principle, the pressure exerted on the first piston is equal to the pressure exerted on the second piston:

which means

where F1, F2 are the two forces and A1, A2 the areas of the two pistons.
The areas of the pistons are:


And the force on the second piston is

, so the force that should be applied on the first piston is
