2.14x 1022 kg
the 22 is a xponet of ten
Add 35 to 215. then divide by 25. you should get x=10
Answer:
The power of top half of the lens is 0.55 Diopters.
Explanation:
Since, the person can see an object at a distance between 34 cm and 180 cm away from his eyes. Therefore, 180 cm must be the focal length of the upper part of lens, as the top half of the lens is used to see the distant objects.
The general formula for power of a lens is:
Power = 1/Focal Length in meters
Therefore, for the top half of the lens:
Power = 1/1.8 m
<u>Power = 0.55 Diopters</u>
Answer:
Since F = G * m1 * m2 / r^2
F = 6.67 * 19E-11 * 2.79 * 9.47 * 10E23 / (1.2 * 10^7)^2
F = 126 * 10E-2 N = 1.22 N
Answer:
the distance between two cars becomes
when blue car travels at legal speed
Explanation:
Initially the relative speed of the two cars is given as


now the relative acceleration of blue car with respect to white car

now the distance between two cars till the relative speed of two cars comes to zero



so the distance between two cars becomes
when blue car travels at legal speed
