An arrow is fired at 5.20 m s−1 at an angle of 22.0° above the horizontal. Find the horizontal component of the initial velocity, expressing your answer in m s−1 to 2d.P.\
Answer:
[tex]4.82ms^{-1}[/tex]
Explanation:
We are given that
Initial velocity, u=5.20m/s
[tex]\theta=22^{\circ}[/tex]
We have to find the horizontal component of the initial velocity.
We know that
Horizontal component of velocity=[tex]ucos\theta[/tex]
Using the formula
Horizontal component of the initial velocity=[tex]5.2cos22^{\circ}[/tex]
Horizontal component of the initial velocity=[tex]5.2\times 0.9272[/tex]
Horizontal component of the initial velocity=[tex]4.82ms^{-1}[/tex]
Hence, the horizontal component of the initial velocity=[tex]4.82ms^{-1}[/tex]

A 6 cm object is 8 cm from a convex lens that has a focal length of 2.7 cm. The image is 4 cm from the lens.
The height of the image is
cm ______
Answer:
3cm
Explanation:
The height of the image will be "3 cm".
Convex lensAccording to the question,
Size of object, u₀ = 6 cm
Distance of object, u = 8 cm
Focal length, f = 2.7 cm
Distance of image, v = 4 cm
Let,
Height of image be "[tex]v_i[/tex]".
We know the formula,
→ Magnification, M = [tex]\frac{Distance \ of \ image}{Distance \ of \ object}[/tex]
By substituting the values, we get
= [tex]\frac{4}{8}[/tex]
= 0.5
hence,
The image's height be:
→ M = [tex]\frac{Height \ of \ image \ (v_i)}{Height \ of \ object \ (u_0)}[/tex]
0.5 = [tex]\frac{v_i}{6}[/tex]
By applying cross-multiplication,
[tex]v_i[/tex] = 0.5 × 6
= 3 cm
Thus the response above is correct.

which of theres is the correct unit for speed? a) m/s- meters per second b) j- joules c) n- newtons
Since the speed formula is = Distance / time
speed = distance /time
speed = metre/ seconds
speed = m/s
Answer:
a) m/s- meters per second
Explanation:
Recall that m/s (meters per second) is the official derived SI unit for speed. That is, it is length (meters) over time (second), hence m/s.
It can't be joules (J), since that is the SI unit for work & energy.
It also can't be newtons (N), since that is the SI unit for force.
Therefore, the correct answer is a) m/s- meters per second.
I hope this made sense to you, if not, feel free to let me know and I can try to provide further assistance.
The driver of a 1.5 x 10^3 kg car is traveling cast at 10 ms and increases its speed to 30 m/s east over 15 seconds. What is the initial and final momentum of the body? What is the net force acting on it?
Answer:
See explanations below
Explanation:
Force = m(v-u)/t
mass m = 1.5*10^3kg = 1500kg
v = 30m/s
u = 10m/s
Time t = 15secs
F = 1500(30-10)/15
F = 1500(20)/15
F = 100 * 20
F = 2000N
Force acting on it is 2000N
momentum = mass * velocity
final momentum = 1500 * 30
final momentum = 45000kgm/s
initial momentum = 1500 * 10
initial momentum = 15000kgm/s
The initial momentum, Final momentum and net force acting on the body are 15000 kgm/s, 45000 kgm/s, and 2000 N respectively.
To solve for initial momentum, Final momentum, and average force, we use the formulas below.
⇒ Formulas
M = mu................. Equation 1M' = mv................... Equation 2F = M'-M/t................ Equation 3⇒ Where:
M = Initial momentum of the carM' = Final momentum of the caru = Initial velocity'v = Final velocityt = timeF = net force acting on the car.From the question,
⇒ For The Initial momentum
m = 1.5×10³ kgu = 10 m/s east⇒ Substitute these values into equation 1
M = 1.5×10³×10M = 15000 kgm/sAlso for Final momentum,
⇒ Given:
v = 30 m/s⇒ Substitute into equation 2
M' = 1.5×10³×30M' = 45000 kgm/sAnd finally for net force,
⇒ Given:
t = 15 seconds⇒ substitute into equation 3
F = (45000-15000)/15F = 30000/15F = 2000 NHence,The initial momentum, Final momentum and net force acting on the body are 15000 kgm/s, 45000 kgm/s and 2000 N respectively.

Beryllium has a charge of +2, and bromine has a charge of –1. Which is the best name for the ionic bond that forms between them? beryllium bromide beryllium bromine bromine berylliumide bromide berylliumide
Answer:
Beryllium bromide
Explanation:
There exists 2 elements in the question
Beryllium Be with valence of +2, and it's a metal
Bromine Br with a valence of -1, and is a non - metal.
Both of them combine together forming an ionic bond:
Be + Br(2) -> BeBr(2)
In naming the compound, we would say that since the first is a metal, beryllium, and the second being a halogen, bromine. We name it by calling the first name together with the last name and changing the last name of the non metal from -ine to -ide.
So we have, Beryllium Bromide.

d Newton's third law of motion
Newtons third law of motion
Explanation:
According to Newtons third law of motion: Every action has an equal and opposite reaction.
What is Newton's 2nd law dealing with acceleration
Answer:
Newton's second law of motion pertains to the behavior of objects for which all existing forces are not balanced. The second law states that the acceleration of an object is dependent upon two variables - the net force acting upon the object and the mass of the object. The acceleration of an object depends directly upon the net force acting upon the object, and inversely upon the mass of the object.

0.1 Hz the approximate frequency of the wave shown.
What is Frequency?In physics, frequency is the number of waves that pass a fixed point in a unit of time as well as the number of cycles or vibrations that a body in periodic motion experiences in a unit of time.
After moving through a sequence of situations or locations and then returning to its initial position, a body in periodic motion is said to have experienced one cycle or one vibration. See also basic harmonic motion and angular velocity.
The frequency is 2 per second if the period, or time interval, needed to complete one cycle or vibration is 1/2 second; it is 100 per hour if the duration is 1/100 of an hour.
Therefore, 0.1 Hz the approximate frequency of the wave shown.

How does physical fitness best reflect having a scientific foundation (connected to science)?Explain
Explanation:
Physical fitness is a state of health and well-being and, more specifically, the ability to perform aspects of sports, occupations and daily activities. Physical fitness is generally achieved through proper nutrition, moderate-vigorous physical exercise, and sufficient rest.
Physical fitness is generally achieved through exercise. Photo shows Rich Froning Jr. – four-time winner of "Fittest Man on Earth" title.
Before the industrial revolution, fitness was defined as the capacity to carry out the day’s activities without undue fatigue. However, with automation and changes in lifestyles physical fitness is now considered a measure of the body's ability to function efficiently and effectively in work and leisure activities, to be healthy, to resist hypokinetic diseases, and to meet emergency situations.

The Gulf Stream is an ocean current that runs from the southern tip of Florida up the eastern coast of the U.S. And ends in the North Atlantic. How would this Northern flowing stream affect the coast of Europe?
Answer:
The Northern flowing stream will affect the coast of Europe by making climate of Western Europe and Northern Europe to be warmer than other areas that are located around the same latitude and this is simply because of the North Atlantic Current
Explanation:
The Northern flowing stream will affect the coast of Europe because the North Atlantic current causes the Gulf stream to be split into two ( 2 ) and the Northern stream which is a warm stream crossing over to Northern Europe.

You have 1.2kg of (AU)gold (that's quite a bit of money at $1839/ounce). Using a heat source you apply 3096 J to the gold and record the Temperature rise from 20C to 40C. What is the specific heat of (AU)Gold?
Answer:
129 J/Kg°C
Explanation:
Given :
Mass of gold, m = 1.2kg
Quantity of heat applied, Q = 3096 J
Temperature, t2 = 40°C
Temperature, t1 = 20°C
Change in temperature, dt = (40-20)°C = 20°C
Using the relation :
Q = mcdt
Where, C = specific heat capacity of gold
3096 = 1.2kg * C * 20°C
3096 J = 24kg°C * C
C = 3096 J / 24 kg°C
C = 129 J/Kg°C
