(a) 764.4 N
The weight of the astronaut on Earth is given by:
where
m is the astronaut's mass
g is the acceleration due to gravity
Here we have
m = 78.0 kg
g = 9.8 m/s^2 at the Earth's surface
So the weight of the astronaut is
(b) 21.1 N
The spacecraft is located at a distance of
from the center of Earth.
The acceleration due to gravity at a generic distance r from the Earth's center is
where G is the gravitational constant and M is the Earth's mass.
We know that at a distance of r = R (at the Earth's surface) the value of g is 9.8 m/s^2, so we can write:
(1)
the acceleration due to gravity at r=6R instead will be
And substituting (1) into this formula,
So the weight of the astronaut at the spacecratf location is
I think it will all be gone and people will be living in space
Answer:
A. proton-driven rotation of the Fo subunit, which causes F1 to change conformation due to that rotation, allowing ADP to be phosphorylated to ATP
Explanation:
To answer the question we need to understand the following.
What is ATP synthase?
- ATP synthase is an enzyme that is found in the electron transport chain which is the final phase of cellular respiration.
What is the Role of ATP synthase?
- The role of ATP synthase is to synthesize ATP which is the main storage energy molecule in the cells.
How does ATP synthase allow production of ATP?
- Production of ATP by ATP synthase complex is through oxidative level phosphorylation.
- The flow of protons down the concentration gradient into the mitochondrion matrix through ATP synthase. This drives the rotation of ATP synthase thus catalyzing the phosphorylation of ADP to ATP.
Answer:
<h2>
Epicenter</h2>
Explanation:
-The hypocenter is the point within the earth where an earthquake rupture starts. The <em>epicenter</em> is the point directly above it at the surface of the Earth. Also commonly termed the focus.
-The location below the earth's surface where the earthquake starts is called the hypocenter, and the location directly above it on the surface of the earth is called the <em>epicenter</em>. Sometimes an earthquake has foreshocks.
