<h3>
<u>Where</u><u>:</u></h3>
<u>m</u><u> </u><u>is mass</u>
<u>And c is a constant for speed of light</u>
For the first part of the trip:
we have velocity = 960 km/hr and distance = 2250 km
velocity = distance / time
time1 = distance / velocity = 2250 / 960 = 2.34375 hours
For the second part of the trip:
we have velocity = 805 km/hr and distance = 1320 km
velocity = distance / time
time2 = distance / velocity = 1320 / 805 = 1.63975 hours
For the total trip:
we have:
total distance covered = 2250 + 1320 = 3570 km
total time taken = 2.34375 + 1.63975 = 3.9835 hours
average velocity = total distance / total time
average velocity = 3570 / 3.9835 = 896.1968 km/hr
Answer:
water
Explanation:
water is 1000 kg/m3 while air is 1.225 kg/m3
Answer:
18.75
Explanation:
p=mv, where p is momentum, m is mass, and v is velocity. For the car:
p=1200*2.5=3000
For the deer:
3000=160*v
v=18.75m/s
Hope this helps!
Answer: See explanation
Explanation:
Simple machine is a machine that has few moving parts or may also have no moving parts and they are usually used to make ones work easier. Examples include wheel and axle, wedge, pulley, lever, screw or an inclined plane.
Their advantages include:
• Less energy is required to perform a particular work.
• It makes work easier.
• It makes work faster.
• Simple machine enable one to do things that might have been difficult to achieve or do.
