Antonio (883 N) does a push-up lifting his body a total of 0.6 meters (down and back up). If this process generated 375 Watts of power, how long did it take her to complete the push-up?
Answer:
Time = 1.413 seconds.
Explanation:
Given the following data;
Force = 883N
Distance = 0.6m
Power = 375 Watts
To find the time;
First of all, we would find the work done by Antonio.
Workdone = force * distance
Workdone = 883 * 0.6
Workdone = 529.8 Joules.
Now, to find the time;
Time = workdone/power
Substituting into the equation, we have
Time = 529.8/375
Time = 1.413 seconds.
Therefore, it took her 1.413 seconds to complete the push-up.
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.

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.

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]

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.

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.

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

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.
