Anastasy [175]

Answer:

Explanation:

A pressure that causes the Hg column to rise 1 millimeter is called a torr. The term 1 mmHg used can replaced by the torr.

1 atm = 760 torr = 14.7 psi.

A.

120 mmHg

Psi:

760 mmHg = 14.7 psi

120 mmHg = 14.7/760 * 120

= 2.32 psi

Pa:

1mmHg = 133.322 Pa

120 mmHg = 120 * 133.322

= 15998.4 Pa

B.

80 mmHg

Psi:

760 mmHg = 14.7 psi

80 mmHg = 14.7/760 * 80

= 1.55 psi

Pa:

1mmHg = 133.322 Pa

80 mmHg = 80 * 133.322

= 10665.6 Pa

A golfer hits a golf ball with a velocity of 36.0 meters/second at an angle of28.0°. if the hang time of the golf ball is 3.44 s
eduard
The range of a projectile is the maximum horizontal distance between the point of origin to the end point. It can be calculated through the equation,
                 range = v²sin2θ/g
where v is the initial velocity, θ is the angle, and g is the gravitational constant. 
Substituting the known values,
                 range = (36 m/s)² x (sin2(28°)) / 9.8 m/s²
                 range = 109.64 m
Thus, the range of the golf ball is approximately 109.64 m.

Describe the proton gradient generated by the electron transport chain
Oksana_A [137]

Answer:

The proton gradient produced by proton pumping during the electron transport chain is used to synthesize ATP. Protons flow down their concentration gradient into the matrix through the membrane protein ATP synthase, causing it to spin (like a water wheel) and catalyze conversion of ADP to ATP.

Pls help me pls<br>pls use the points as my thank you ​
Ivanshal [37]

Answer:

A

Explanation:

In section A, she is moving in constant speed because there's a flat line which indicates speed remained same as time passed. In section c, there's a flat line but look at y axis for this one, it is 0 which means there's no speed during this part. B and D have varying speeds as there is a change in y axis variables as time passes.
