<h2>Answer: 10.52m</h2><h2 />
First, we have to establish the <u>reference system</u>. Let's assume that the building is on the negative y-axis and that the brick was thrown at the origin (see figure attached).
According to this, the initial velocity 
has two components, because the brick was thrown at an angle 
:
(1)
(2)
(3)
(4)
As this is a projectile motion, we have two principal equations related:
<h2>
In the x-axis:
</h2>
(5)
Where:
is the distance where the brick landed
is the time in seconds
If we already know 
and 
, we have to find the time (we will need it for the following equation):
(6)
(7)
<h2>
In the y-axis:
</h2>
(8)
Where:
is the height of the building (<u>in this case it has a negative sign because of the reference system we chose)</u>
is the acceleration due gravity
Substituting the known values, including the time we found on equation (7) in equation (8), we will find the height of the building:
(9)
(10)
Multiplying by -1 each side of the equation:
>>>>This is the height of the building
Explanation:
Yes, in order to determine whether two geometric figures are identical or not we tend to rotate one of the figure clockwise or anti clock wise mentally. However, in clockwise rotation larger the angel more will be the time taken for instance, it will take longer to rotate 120° than to rotate 40°. Whereas in anti clockwise ration it will be vice versa.
Answer:
If jack is in the piece of furniture it would submerge.
Explanation:
The piece of furniture would submerge if the weight applied on the furniture is greater than the maximum buoancy force the water can provide.
maximum buoacy force = density of liquid × volume submerged× acceleration due to gravity.
= 
v = area × thickness of pine
= 0.075 
therefore buoancy force = 1025×0.075×9.8 N
= 753.375 N
weight of rose alone = 46×9.8 N = 450.8 N
weight of jack alone = 58×9.8 = 568.4 N
weight of pine = density of pine × volume of pine
= 350 × 0.075= 26.25 N
weight of pine + weight of rose = 450.8+26.25=477.05 N
weight of pine + rose + jack = 477.05 + 568.4 = 1045.45 N
therefore if jack is in the piece of furniture it would submerge.
I think the answer is A
Explanation:
the bus has more kg than the car so. the bus need to stop first
The distance that is not a wavelength in the image is C to E.
<h3>What is wavelength?</h3>
Wavelength is the distance between two successive crests or two successive trough or crest to trough.
It is also the distance over which the wave's shape repeats.
Based on the image, the following are wavelengths;
- A to E, this is wavelength because it is between a crest and a trough.
- B to F, this is wavelength because it is between two successive crest.
- D to H, this is wavelength because it is between two successive trough.
Thus, the distance that is not a wavelength in the image is C to E.
