The answer is True
The center of the orbital ellipse is always at one point of the suns center ( meaning the suns center is always found or located at one of the focuses of the orbital ellipse )

Answer:

True

Kepler's First Law: each planet's orbit about the Sun is an ellipse. The Sun's center is always located at one focus of the orbital ellipse. The Sun is at one focus. The planet follows the ellipse in its orbit, meaning that the planet to Sun distance is constantly changing as the planet goes around its orbit.

In principle, the motion of a simple pendulum and an object on an ideal spring can both be used to provide the basic time interv

stich3 [128]

Answer:

Explanation:

The time period of the pendulum containing simple pendulum is given by

$T = 2\pi \sqrt{\frac{L}{g}}$

where, L is the length of the pendulum and g is the value of acceleration due to gravity.

The time period of the clock using the spring mechanism is given by

$T = 2\pi \sqrt{\frac{m}{k}}$

where, m is the mass of the block attached to the spring and k is the spring constant.

here we observe the time period of the pendulum depends on the value of acceleration due to gravity. The value of acceleration due to gravity decreases as we go on the heights that means when the clock is taken to the mountain, the value of g decreases and thus, the value of time period increases and the clock runs slow.

So, the clock containing the spring system gives the accurate reading rather than the clock containing simple pendulum.

You are designing a hydraulic lift for a machine shop. the average mass of a car it needs to lift is about 1500 kg. you wish to

Alchen [17]

You want the force/area ratio to be the same for both pistons to keep constant pressure. Since 1500/450=3.333, you will need to pick the two sets of dimensions such that (assuming the pistons are rectangular) the product of the pair of dimensions for the 1500 kg piston is 3.333 times the product of the pair of dimensions for the 450 kg piston.
