HURRY!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!One object has a speed of 1 mph and another object has a speed of 3 mph. If the masses are the same, which of the following is true about their kinetic energy?

Question 7 options:

Their speeds are the same.

the object with the greater speed has greater kinetic energy

the object greater speed has the lower kinetic energy

the object with the smaller mass has the greater kinetic energy

Answers

Answer: Option (B) is the correct answer.

Explanation:

Kinetic energy is the energy due to the motion of an object.

Mathematically, K.E = $(1)/(2)mv^(2)$

where m = mass

v = velocity

Therefore, an object whose velocity is more will have more kinetic energy.

Thus, we can conclude that out of the given options, the object with the greater speed has greater kinetic energy is true about their kinetic energy.

The object with the greater speed has greater kinetic energy

What is the majority of 0.50 g of na dissolved in a 1.5 L solution

Answers

The correct answer is 0.014467 M.

Molarity is defined as the number of moles present in a liter solution, that is, number of moles / liter solution.

The molar mass of sodium (Na) is 23.0 g/mol

Thus, 1 mole of Na contains 23.0 g

Now, x moles of Na contains 0.50 g

Moles = 0.50 × 1 / 23.0

Moles = 0.50 / 23.0

= 0.0217 moles of Na

Molarity = Number of moles / liters of solution

= 0.0217 / 1.5

= 0.014467 M

Describe the conditions that are necessary for snow to fall

Answers

the temperature had to be cold both up in the clouds where snowflakes form and down at ground level. If air near ground level is too warm the snow will melt on way down changing to rain or freezing rain also Moisture is needed to form clouds and precipitation.

temperature has to be at least below 34° for snow to fall and it has to be a day where rain would fall
