Answer:

Convert all the times to either hours or seconds

Explanation:

One time unit is in hours, and the other is in seconds.  In order to do the math, the units need to be the same.  So you either need to convert hours to seconds, or seconds to hours.

Answer:

-Convert all the times to either hours or seconds.

Explanation:

Given,

d= (0.90km) + (12.5km/h) \times (31.5s)

While doing a mathematical calculation all the units should be same otherwise the result will not be correct. Here two units of time i.e. second and hour are being used. We will convert the second to hour by dividing it by 3600 as there are 3600 seconds in one hour. The distance will be,

d= (0.90km) + (12.5km/h) \times (\frac{31.5}{3600}h)

d= 0.90 + 12.5 \times \frac{31.5}{3600}

d= 0.90 + \frac{393.75}{3600}

d= 0.90 + 0.109

d= 1.009 km

Ugo [173]

Applying Newtons version of Kepler's third law or the orbital velocity law to the star orbiting 40000 light years from the center of the Milky Way Galaxy allows us to determine the mass of the Milky Way Galaxy that lies within 40000 light years in the galactic center.

<h3></h3><h3>What is orbital velocity law?</h3>

The orbital velocity law states that, the orbital velocity is directly proportional to the mass of the body for which it is being calculated and inversely proportional to the radius of the body. Earths orbital velocity near its surface is around 8km/sec if the air resistance is disregarded.

In space exploration, orbital velocity is a crucial topic. Space authorities heavily rely on it to comprehend how to launch satellites. It aids scientists in figuring out the velocities at which satellites must orbit a planet or other celestial body to prevent collapsing into it. The speed at which one body orbits the other body is known as the orbital velocity. The term "orbit" refers to an object's consistent circular motion around the Earth. The distance between the object and the earth's centre determines the orbit's velocity.

If tides occur twice a day in most places. How much time is there between a morning high tide and the next high tide?
algol13

About 12 hours is the time between a morning high tide and the next high tide

Explanation:

The Earth’s rotation happens between two tidal bulges  

The “periodic rise and fall” of the surface water levels of the ocean is called tides. The gravitational action and interaction on the earth by the sun and the moon causes these tides. Different regions of the World experiences different patterns of tides like the diurnal, semi-diurnal etc.

When there is one high and one low tide occurring on a lunar day, then it is diurnal pattern. Semi-diurnal pattern occurs when there are two equal high and low tides on a single lunar day.

Since the Earth’s rotation happens between two tidal “bulges” on each lunar day, the coastal areas can experience two high and two low tides in every 24 hours plus 50 minutes.

Accordingly the time between two high tides would be 12 hours plus 25 minutes. Similarly, the time gap between a high to low tide would be 6 hours plus 12.5 minutes.
