1. An elephant has a mass of 5,500 kg. What is the elephant's weight?
Write equation here:
Answers
Answer:
12125.42 Lbs.
Explanation:
The weight of the elephant is 53,900 N
The given parameters;
mass of the elephant = 5,500 kg
The weight of the elephant is calculated as;
Weight = mg
where;
m is the mass of the elephant
g is acceleration due to gravity = 9.8 m/s²
The weight of the elephant is calculated by substituting the given parameters;
Weight = 5,500 x 9.8 = 53,900 N
Thus, the weight of the elephant is 53,900 N

C. 9 Hz
D. 20Hz
Answers
Answer:
its B
Explanation:
i just took the test
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
Answers
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 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?
Answers
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.

A dolphin can hear sounds with frequencies up to 280 kHz. What is the
speed of sound in water if a wave with this frequency has a wwavelength
of 0.51 cm?
Answers
Answer:
1428 m/s
Explanation:
Given that,
The frequency hear by a dolphin, f = 280 kHz
We need to find the speed of sound in water if a wave with this frequency has a wavelength of 0.51 cm.
The formula for the speed in terms of wavelength and frequency is given by :
[tex]v=f\lambda\\\\v=280\times 10^3\times 0.51\times 10^{-2}\\\\v=1428\ m/s[/tex]
So, the speed of sound in water is 1428 m/s.

Answers
Answer:
If the mass of both of the objects is doubled, then the force of gravity between them is quadrupled; and so on. Since gravitational force is inversely proportional to the square of the separation distance between the two interacting objects, more separation distance will result in weaker gravitational forces.

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?
Answers
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
