Answer:
speed of molecule ∝ 1/mass of molecule.
Explanation:
The velocities of the molecules depend on their masses. That's because if the molecules are large in size, their velocity is slower. Therefore their velocity is quicker when their size is small, since the molecules can move faster.
Therefore , it can be written as
speed of molecule ∝ 1/mass of molecule.
Answer:
She is not getting a good deal.
Explanation:
The equation that relates heat with mass, specific heat and temperature change of an object is 
.
Always convert temperature to Kelvin, although in our case it's not necessary because the 
will be the same, and we will leave the mass in grams because we will be getting 
units for specific heat, which we can compare to the one given for gold.
We then calculate the specific heat of the object in question:
Which shows it's not gold.
Formula for Velocity = DISTANCE traveled/TIME to travel distance + direction
For this one, we can use mph(miles per hour) as unit.
v = 1,000 miles / 336 hours (2 weeks = 24 hours x 14 days = 336 hrs)
= 2.98 mph North
or we can use kph (kilometers per hour)
v = 1609.34 km / 336 hours (1 mile = 1.60934 km)
= 4.79 kph North
Answer:
The answer to your question is Nonmetals
Explanation:
Nonmetals they are bad conductors of heat and electricity except graphite.
Metalloids they are less conductors of electricity than metals.
Noble gases they conduct electricity.
Halogens they are not metals and do not conduct electricity.
From this information, we conclude that Oxygen and Selenium are nonmetals.
-Try one new workout every month. Keeping the same exact routine when it comes to your fitness is never a good thing.
-More water
With any diet, the most important thing to remember is to stay hydrated. Drinking water will support your body with digestion, transporting nutrients to your bones and muscles, and even improving cognitive function.
Ideally, you want to drink about half your body weight in ounces per day, i.e. if you weight 150 pounds, you should drink 75 ounces of water a day.
-Stretching
The benefits are vast and the repercussions of failing to stretch can be dramatic.
Do yourself a favor and always stretch before and after a workout. This will promote a healthy cool down, improve flexibility, and reduce next day aches. Failure to stretch can lead to injures and muscle damage.
-Body Fat
This may seem like an obvious one, but it is one of the most important steps to a healthier you. Reducing your body fat has a lot of benefits such as:
Improved joints and tendons
Lowered risk of diabetes
Reduced risk of heart disease
Reduced inflammation
Better performance and endurance
Improved appearance and confidence
Better hormonal profiles in your body
Remember, it is not a race to see how quickly you can decrease your body fat. Healthy weight loss is around 1-2 pounds a week for your fitness goals.[2]
Crash dieting or pushing yourself too much in the gym can lead to you achieving an unrealistic target, and you may find yourself gaining all the weight you have lost.
Think of it as a lifestyle, and take it slow and steady.
