Answer:
Explanation:
calculate the momentum before the puck hits the goalie: momentum = mass*velocity
p = 0.17*54.9
p = 9.333 kg.m/s
Because the final momentum is zero, the change in momentum is also 9.333, which is also called impulse.
Apply impulse = Force*time
9.333 = 3.62*10^-3*F
F = 2578.17679558
Therefore the average force exerted is 2578N
First few instances I performed goalie, I wore a participant helmet with cage + neck protector. (Cooper HH 3000 if it concerns) in case you could purchase some extra padding and function it placed into the goalie helmet. Use of a "doo-rag" (kinda feels like a yamulkha) will soak up a number of the surplus room as properly. the burden is greater on the grounds which you at the instant are not used to it. yet in the top, it is your protection on the line.
<h3>Answer</h3>
1.1772 N
<h3>Step by Step Explanation</h3>
Given in the question,
mass of an object = 0.12 kg
To find the weight of this object we will use formula
weight = mass x acceleration due to gravity
We know that acceleration due to gravity on earth is constant = 9.81 m/s²
So,
weight = 0.12 x 9.81
= 1.1772 N
Since it is not mention that were the object is so i assume that it is on earth but if it is on moon then acceleration due to gravity will be 1.625 m/s²
Answer:
3.56 mi
Explanation:
from the question we are given the following:
first angle of depression = 22 degrees
second angle of depression = 24 degrees
find the height of the hot air baloon
First we have to take note of the following
- That the distance between two successive mileposts is 1 mile
- The angle of elevation from the mileposts will be 22 degrees and 24 degrees because they are alternate angles with the angles of depression
- I attached a diagram to to illustrate the above points
for the smaller triangle tan 24 = \frac{h}{p}
h = p × tan 24 ... equation 1
for the bigger triangle tan 22 = \frac{h}{p +1}
h = {p +1} x tan 22 ..... equation 2
now equating the two equations for h we have
p x tan 24 = {p+1} x tan 22
0.45 p = 0.4 {p+1}
1.125 p = p + 1
1.125 p - p = 1
p = \frac{1}{0.125} = 8
now we can substitute the value of p into equation 1
h = p x tan 24
h = 8 x tan 24 = 3.56 mi
The microgram is the greater mass. It takes 1,000 nanograms to make just one. One microgram is 999 nanograms bigger than one nanogram.
