Answer: actually the fastest 100m is 9.58, because i run at a 9.86
Explanation: but 10.44 is like 15 mph, 9.58 is 28 mph
They live half their lives in water and most of their life on land
Answer:
7.81 m/s
Explanation:
Given,
initial speed, u = 10.2 m/s
angle of inclination, θ = 40°
time, t = 2.12 s
Horizontal component of the velocity:
In projectile motion horizontal component of the velocity remain same at every point because there is no acceleration.
So, Velocity at the Pinnacle is equal to 7.81 m/s
Answer:
The weight of the person would increase
Explanation:
The Universal Law of Gravitation gives the magnitude of the force between the masses of two objects (m1 and m2) separated a given distance "d" as:
where G is the universal gravitational constant.
Our weight on Earth is this force between the Earth (of mass M) and ourselves (our mass m) at a distance that is the Earth's radius R:
Now, if we keep all the values equal (mass of the Earth M and our mass m) except for the distance between the center of the Earth and our center of gravity (the radius of the Earth), we are going to have now a smaller radius (r) in the formula above:
and dividing by a smaller number (r is smaller than R), will render a larger quotient. This means that the actual force (weight) will become larger, so the weight would clearly increase.

The totality of fossils, both discovered and undiscovered, and their placement in fossiliferous (fossil-containing) rock formations and sedimentary layers (strata) is known as the fossil record</span>
