Answer:
<em>Weight = 34.3N</em>
Explanation:
Weight = mass * gravitational acceleration
Gravitational acceleration (on Earth) = 9.8
<em>so,</em>
Weight = 3.5 * 9.8
Weight = 34.3N
Take the radius of the Earth 6 370 km.Then:
The semimajor axis:a = 6 370 + 360 = 6 730 km
Semiminor axis:b = 6 370 + 180 = 6 550 km
Eccentricity:ε = √ (a2+b2) / a = √ (6 7302+65502) / 6 730 ≈ 1.4
The answer is b. It serves as a link between membrane proteins on adjacent membranes.
If the elevator falls from a height of 240 meters and Superguy is 1 km away, he will have 6.5 seconds to save Lois, which means that his average speed must be 150 meters per second.
<h3>What is the average speed?</h3>
The total distance traveled by an object divided by the total time taken is the average speed.
The average speed of an object indicates the pace at which it will traverse a distance. The metric unit of speed is the meter per second.
Given data:
Distance of super guy from the tower = 1.00 km
height(h)= 240 m
From the Newtons' second equation of motion:
Distance is the foundation as the product the velocity and time;
D=ut
u=d/t
u=1000/t
u=1000/6.5
u=150 m/sec
Hence, he will have 6.5 seconds to save Lois, which means that his average speed must be 150 meters per second.
