30 unit If the value of an angle with the x-axis of a vector is 70 °, the value of the angle with the y axis is 60, what is the value of the angle with the z-axis?
Answer: [tex]37.28^{\circ}[/tex]
Explanation:
Given
Angle made with the x-axis is [tex]\alpha=70^{\circ}[/tex]
Angle made with the y-axis is [tex]\beta=60^{\circ}[/tex]
Suppose angle made with z-axis is [tex]\gamma[/tex]
[tex]\therefore \cos^2\alpha+\cos^2\beta+\cos^2\gamma =1[/tex]
Inserting values
[tex]\Rightarrow \cos^2(70^{\circ})+\cos^2(60^{\circ})+\cos^2\gamma=1\\\Rightarrow 0.1169+0.25+\cos^2\gamma=1\\\Rightarrow \cos^2\gamma=0.6331\\\Rightarrow \cos \gamma=0.7956\\\Rightarrow \gamma=37.28^{\circ}[/tex]

kinetic energy of 2004
о a
What is
the speed of the car?
What is it
Answer:
v = 1.63 m/s
Explanation:
Given that,
The mass of a car, m = 1500 kg
The kinetic energy of a car, K = 2004 m/s
We need to find the speed of a car. The formula for the speed of a car is given by :
[tex]K=\dfrac{1}{2}mv^2\\\\v=\sqrt{\dfrac{2K}{m}} \\\\v=\sqrt{\dfrac{2\times 2004}{1500}} \\\\v=1.63\ m/s[/tex]
So, the speed of the car is equal to 1.63 m/s.

A bullet with a mass of 0.020 kg collides with a 2.5 kg wooden block at
rest. After the collision, the bullet and the block travel at a speed of 1.2
m/s. What is the velocity of the bullet BEFORE the collision? *
Answer:
151.2 m/s
Explanation:
m1 = 0.020 kg
m2 = 2.5 kg
vf = 1.2 m/s
m1v1 +m2v2 = (m1 +m2)vf
0.020v1 + 0 = (0.020 +2.5)(1.2)
---> 151.2 m/s
A ball has a 17 J of kinetic energy and its mechanical energy ls 25 Joule.
a. Find the gravitational potential energy of the ball.
Question:
A ball has a 17 J of kinetic energy and lB mechanical energy is 25 Joule
a. Find the gravitational potential energy of the ball.
b. if the ball has a mass of 3.2 kg, what is its height above the ground?
c. What is the speed of the ball?
Answer:
a. = 85
b. h = 0.25 m
c. = 3.26 m/s
Explanation:
Part A
PEgrav = m ו g • h
In the above equation, m represents the mass of the object, h represents the height of the object and g represents the gravitational field strength (9.8 N/kg on Earth) - sometimes referred to as the acceleration of gravity. So, to find:
GPE = ME - KE = 25 - 17 = 85
Part B
The formula simplifies to: h max = h + V₀² / (2 × g) and the time of flight is the longest.
The vertical velocity is equal to 0 (Vy = 0), and that's the case of horizontal projectile motion.
The equation may be written as:
GPE = mgh
8 = 3.2 × 10 × h
h = 0.25 m
Part C
The ball speed is calculated by dividing the distance by the time. If the time was 3 seconds, the average speed will be 60/3 = 20 feet per second (6.1 m/sec). KE = 1/2 MV²
17 = 1/2 × 3.2 x V²
V = 17 ÷ 1.6
Note, this is only the average ball speed, the speed of the ball at the time of release would be greater.

Answer:
Magnetic field patterns of two permanent magnets.
Explanation:
From the attached picture, it can be observed that iron filings has been caused to align with respect to the magnetic fields of permanent the magnets. The concentration of the filings at some definite spots shows the poles of the magnet. This forms a magnetic field pattern.
This simply illustrates the effect of magnetic fields on iron filings by placing magnets below a paper or cardboard with iron filings on the top of the paper. The magnetic field pattern would be lost if the magnets are removed.

: where are you likely to find a cooling plant located in the duckwork? A. single family home B. A large apartment C. large factory D. A medium sized offices
Answer:
Option C
Explanation:
In a large sized factory, it is essential to create cooling system based on duct work because it can then be able to regulate cooling of any section of the factory from one place. Also, ductwork cooling is preferred in large spaces such as big offices building, towers, factories etc.
Hence, option C is correct
If an object that was held steady (0 speed) and then dropped, how many meters would it fall in one second?
Answer:
h = 4.905 m
Explanation:
In order to find the distance covered by the object in 1 second, we can use the second equation of motion:
[tex]h = v_i t + \frac{1}{2}gt^2\\[/tex]
where,
h = distance covered = ?
vi = initial speed = 0 m/s
g = acceleration due to gravity = 9.81 m/s²
t = time = 1 s
Therefore,
[tex]h = (0\ m/s)(1\ s)+\frac{1}{2}(9.81\ m/s^2)(1\ s)^2\\\\[/tex]
h = 4.905 m
Which of the following electrical components protects your home from excessive flow of current in the electrical wires?
- resistor
- fuse
- transistor
- capacitor
Answer: the correct option is FUSE.
Explanation:
Current Electricity consists of fast moving negatively charged electrons which travels in materials that allows the flow of electrons called conductors. In the generation of Electricity for distribution, two types of currents are being generated. It's either an Alternating current ( A.C) or a Direct Current ( D.C.). An A.C. consists of electric charges that constantly changes its position and direction of flow of voltage and current while D.C. the electric charge flow in one direction. For the safety of devices of the end users of the electric current ( either A.C. or D.C) generated, a FUSE is usually used to protect the appliances from too much flow of electric current.
A fuse is therefore defined as a safety device that protects appliances( such as televisions, refrigerators, computers) from current overload or voltage fluctuations which can cause damaging effects. It is made up of thin strip or strand of metallic wire with noncombustible material. These devices are usually connected in series with the components to be protected from current overload. This is so because, when there is high or excessive current, the fuse melts and it opens the circuit and disconnects it from the power supply. Some of the types of fuse includes A.C fuse and D.C. fuse.

A mosquito's wings create a buzzing noise with a frequency of 1050 Hz. If you hear a mosquito buzzing with a frequency of 1034 Hz, at what velocity is the mosquito travelling with respect to you (in m/s)?
NO LINKS
Answer:
5.26 m/s
Explanation:
Given that,
The frequency of mosquito's wings, f = 1050 Hz
The observed frequency = 1034 Hz
We need to find the velocity of the mosquito travelling with respect to you. We have a formula to find it such that,
[tex]v=\dfrac{v}{\dfrac{f'}{f}}-v[/tex]
Where
v is the speed of sound
So,
[tex]v=\dfrac{340}{\dfrac{1034}{1050}}-340\\\\v=5.26\ m/s[/tex]
So, the required velocity is equal to 5.26 m/s/

Explanation:
When a liquid occupies a smaller volume, it exerts a higher pressure; when it occupies a larger volume, it exerts a lower pressure.
volume= mass÷density

B- 20÷1.6= 12.5cm³
C- 30÷1.2= 25cm³
D- 40÷0.7= 57.1cm³

The volume of an object as a function of time calculated by V=At^3+B/t,where t is time measured in seconds and V is in cubic meters. Determine the dimension of the constants A and B
Answer:
A = L^3 T^-3 , B = L^3 T
Explanation:
Given: volume ( V ) = At^3 + B/t ------ ( 1 )
dimension of volume = L^3
and the Dimension of time = T
back to equation ( 1 )
L^3 = A * T^3 ------- ( 2 )
also L^3 = B/T ------- ( 3 )
from equation ( 2 )
A = L^3 T^-3
from equation ( 3 )
B = L^3 T
The dimensions of the constants A and B
A = L^3 T^-3 , B = L^3 T
