Explanation:

According to the Newton's law of universal gravitation, the force between two bodies is given by :

$F=G\dfrac{m_1m_2}{d^2}$ ..........(1)

$m_1\ and\ m_2$ are masses

d is the distance between objects

From equation (1), the force of gravity increases when distance decreases or mass increases and the force of gravity decreases when mass decreases or distance increases.

Consider the following examples of homeostatic regulation: In response to an increase in plasma K concentrations, secretion of t

TiliK225 [7]

Answer:

Both are examples of negative feedback regulation.

Explanation:

The maintenance of the homeostasis in the body is controlled by the the feedback regulation of the body. Two main types of feedback regulation are positive regulation and negative regulation.

The negative regulation occurs when the final product of the reactions inhibits the further secretion of that product. In the given examples of aldosterone and calcium mechanism, the secretion of aldosterone and calcium decreases as the normal levels are acheived in the body.

Thus, the answer is both are examples of negative feedback regulation.

Col. John Stapp led the U.S. Air Force Aero Medical Laboratory's research into the effects of higher accelerations. On Stapp's f

Lerok [7]

Answer:

A. $a=203.14\ \frac{m}{s^2}$

B.s=397.6 m

Explanation:

Given that

speed u= 284.4 m/s

time t = 1.4 s

here he want to reduce the velocity from 284.4 m/s to 0 m/s.

So the final speed v= 0 m/s

We know that

v= u + at

So now by putting the values

0 = 284.4 -a x 1.4 (here we take negative sign because this is the case of de acceleration)

$a=203.14\ \frac{m}{s^2}$

So the acceleration while stopping will be $a=203.14\ \frac{m}{s^2}$ .

Lets take distance travel before come top rest is s

We know that

$v^2=u^2-2as$

$0=284.4^2-2\times 203.14\times s$

s=397.6 m

So the distance travel while stopping is 397.6 m.

A(n) 1700 kg car is moving along a level road at 21 m/s. The driver accelerates, and in the next 10 s the engine provides 22000

allochka39001 [22]

The final speed of the car at the given conditions is 30.1 m/s.

The given parameters:

Mass of the car, m = 1700 kg
Velocity of the car, v = 21 m/s
Time of motion, t = 10 s
Additional energy provided by the engine, E₁ = 22,000 J
Energy used in overcoming friction, E₂ = 3,666.67 J

The change in the energy applied to the car is calculated as;

$\Delta E = E_1 - E_2\\\\\Delta E = 22,000 \ J \ - \ 3,666.67 \ J\\\\\Delta E = 18,333.33 \ J$

The final speed of the car is calculated as follows;

$\Delta E = \frac{1}{2} m(v_f^2 - v_0^2)\\\\v_f^2 - v_0^2 = \frac{2\Delta E}{m} \\\\v_f^2 = \frac{2\Delta E}{m} + v_0^2\\\\v_f = \sqrt{ \frac{2\Delta E}{m} + v_0^2} \\\\v_f = \sqrt{ \frac{2\times 18,333.4}{1700} + (21)^2} \\\\v_f = 30.1 \ m/s$

Thus, the final speed of the car at the given conditions is 30.1 m/s.

How does the energy of the marble remain the same at all points on the ramp

Elenna [48]

Answer:

It depends on the potential energy it has ontop of the ramp. The marble has the same potential energy was the kinetic energy without changing the ramp incline or moving it. What kinetic energy shows is what potential energy made it to be, so we look at how the ramp is placed. If the ramp is a steep incline the kinetic energy will be fast. It depends on the weight of the marble too. If the marble is heavy the potential energy will slowly tansition to kinetic energy while a light marble will transition to kinetic energy fast. But marbles are light so there we have it. It basically goes from potential energy to kinetic energy to thermal energy to potential energy. Make me brainliest pls :)
