1. An elephant has a mass of 5,500 kg. What is the elephant's weight?
Write equation here:
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

The available options are:
Mint is a dicot.
Mint is a monocot.
Mint is an angiosperm.
Mint is a bulb plant.
Answer:
Mint is a dicot.
Explanation:
Given the fact that Mint is considered to be a member of Lamiaceae, an angiosperm plant which is characterized by typically having leaves that consist of reticulate vacation and appears like veins in structure. It also has a seed that contains two cotyledons.
Hence, it is considered a DICOT PLANT due to these characteristics. The botanical name of Mint is referred to as Mentha arvensis.

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

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?
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.

B. 0.1 Hz
C. 9 Hz
D. 20Hz
Answer:

Explanation:

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.
