Answer:
1.986 * 10 to the power of 6 (100,000) equals
1,986,000
Power
is calculated by dividing the work done with the time interval of the motion.
Work, on the other hand, is force times the distance traveled. Therefore, we
can calculate as follows:<span>
Power=W/t = mgd/t
90 = 60(9.81)d / 40
d = 6.12 m
Number of steps = 20/6.12 = 3.27 or 3 steps</span>
The "Troposphere" <span>is the layer of the atmosphere in which weather occurs!
It is the lowermost layer of atmosphere, where we live.
Hope this helps!</span>
Answer:
based on my opinion
The smart guys at NASA designed the trajectory such that as they passed Jupiter, they gained some speed by being dragged along by Jupiter
This is called a gravity assist . Voyager 2 picked up about 18 km / s of velocity from that Jupiter gravity assist ...

Answer:
0.098 N
Explanation:
From the question,
Spring scale reading = W-U............... Equation 1
Where W = weight of the cube, U = upthrust.
W = mg
Where m = mass of the cube, g = acceleration due to gravity.
Given: m = 11 g = 0.011 kg, g = 9.8 m/s².
W = 0.011(9.8)
W = 0.1078 N.
From Archimedes principle,
Upthrust = weight of water displaced.
U = (Density of water×volume of metal cube)×acceleration due to gravity.
U = (D×V)g
Given: D = 1000 kg/m², V = 1 cm³ = (1/1000000) = 1×10⁻⁶ m³, g - 9.8 m/s²
U = 1000(9.8)(10⁻⁶)
U = 0.0098 N.
Substitute the value of W and U into equation 1
Reading of the spring scale = 0.1078-0.0098
Reading of the spring scale = 0.098 N
