Answer:
C
Explanation
Because My teacher told me that for an example Florida is hot but in Central America is cold or hot and you don’t need a jacket. I don’t remember much
The Central America is near the equator could explain the above statement.
What is equator?Equator is an imaginary line that passes through the centre of the globe at 0 degrees latitude and at equal distance between the North and South Poles.
Some countries of Central America are situated near the equator. The places near equator have little seasonal variation. These places have same amount of daylight and darkness throughout the year and remain warmer year round. These places near the equator have an alternating dry and rainy seasons.
Hence, we can conclude that option C is the answer.

Which of the following substances cannot be separated?
O homogeneous mixture
heterogeneous mixture
element
O compound
Answer: Elements.
Explanation: Homogeneous and heterogeneous is just if a mixture is uniform or not. Mixtures and always be separated. Compounds are elements that combined which can be broken down again. So I say the logical answer is an element since it's pure and cannot be broken down into other elements or more of it's self.

Help fast. If 1500 joules of energy is used to heat 50g of water with a temperature of 20°C, then what will the final temperature be? (Water’s specific heat is 4.18 j/g°c)
Answer:
27°C
Explanation:
q = 1500 J
m = 50g
c = 4.18 J/g°C
q = m·c·ΔT
ΔT = [tex]\frac{1500J}{50g*4.18\frac{J}{gC} } = 7C[/tex]
ΔT = final temperature - initial temperature
Final temp = 20 + 7 = 27°C
If 5,800 j of energy are applied to a 15.2 kg piece of lead, by how much does the temp change if the specific heat of lead is 0.128
Answer:
The answer will be 2.98K
Explanation:
Using the formula:
Q = mc∆T
Q= 5,800 (heat in joules)
m= convert 15.2kg to g which is 15200g (mass in grams)
c= 0.128 J/g °c (Specific heat capacity)
∆T= what we need to find (temperature change)
5800J = 15200g x 0.128 x ∆T
= 2.98K

How many inches/second are in
1.73 meters/minute?
A. 68.1 in./s
B. 0.0288 in./s
C. 1.14 in./s
D. 2.64 in./s
Answer:
1.73 meters / minute = 1.14 inches / second
Explanation:
The number of inches present in 1.73 meters/minutes is equal to 1.14 inches/seconds.
What is conversion factor?Conversion factor is a quantity which is get multiplied or divided with an any other given quantity to convert the given quantity into any other quantity.
Given quantity = 1.73 m/min
We know that, 1 meter = 39.37 inches
1.73 m/min = 1.73 × 39.37 = 68.11 inches/min
Also we know that, 1 min = 60 min to convert the above quantity into sec we should divide that by 60 as:
68.11 inches/min = 68.11 / 60 = 1.135 inches/sec (1.14)
Hence the required quantity is 1.14 in./s.

Heat capacity of a material is dependent upon the material's mass.
True or false?
Hello
Answer:
True.This quantity is known as the specific heat capacity (or simply, the specific heat), which is the heat capacity per unit mass of a material. Experiments show that the transferred heat depends on three factors:
(1) The change in temperature,
(2) the mass of the system.
(3) the substance and phase of the substance.
Velocity and speed are both measurements of how fast something is moving however velocity is different from speed because
A) velocity and speed are the same thing
B) velocity is usually faster than speed
C) The velocity of an object also tells us the direction something is moving
D) velocity is how fast something is changing its speed
Answer:
C
Explanation:
Velocity is a vector quantity I.e it has magnitude and direction
Speed on the other hand is a scalar quantity I.e it has only magnitude

smaller, cooler, and more luminous
larger, hotter, and less lumulous
larger, cooler, and more luminous
Answer:
Larger, cooler, and more luminous.
Betelgeuse is red in color, and that means that the surface of it is cooler than the sun (bluish white is hottest, and red is lowest). It is also common knowledge that it is larger, so the correct option would be D. Hope this helped :)

wave has a frequency of 5hz and a wavelength of 25 m/s.
what is the speed of the wave
Answer:
125m/s
Explanation:
speed= wavelength×frequency
= 25×5
=125
The speed of the wave will be 125 m/s.
What is speed?The magnitude of an object's rate of change of position with time, or the magnitude of change of position for each unit of time, is its speed; it can be considered as a scalar quantity.
Speed = wavelength × frequency
Calculation of speed is shown below:
It is given that wavelength = 25 m/s, frequency = 5 hz.
Speed can be calculated by using the formula:
Speed = wavelength × frequency
speed = 25m/s × 5 hz
speed = 125 m/s
