<u>Weight = (mass) x (acceleration of gravity)</u>
Weight = 63 N
On Earth, acceleration of gravity = 9.8 meters per second².
63 N = (mass) x (9.8 meters per second²)
Divide each side of the equation by (9.8 m/s²).
63 / 9.8 = Mass
<em> Mass = 6.4 kilograms</em>
There's no info about the cars starting off differently, so as far as we know they have been side by side all the way.
<span>So from the last telephone pole: </span>
<span>(a) and (b): the displacement of both cars is 65.5m
the average speed for both car is 65.5m/5.0s = 13.1m/s</span>
Answer:
<em>The table is 2.08 m high</em>
Explanation:
<u>Horizontal Motion</u>
When an object is thrown horizontally with a speed vo from a height h, the range or maximum horizontal distance traveled by the object can be calculated as follows:
If we know the range d = 0.15 m and the speed v = 0.23 m/s, we can solve the above equation for h:
The table is 2.08 m high
THIS IS NOT THE EXACT ANSWER BUT IT MIGHT HELP
The cover slips serves two purposes: (1) it protects the microscope's objective lens from contacting the specimen, and (2) it creates an even thickness (in wet mounts) for viewing.
The overall change in velocity is just 20m/s.
