Which of the following are density labels? (you can pick more then one!)
kg/L
g/m
g/mL
cm^3/g
Answer:
The correct options are kg/L and g/mL
Explanation:
The formula for density can be expressed as
Density = mass ÷ volume
where the mass can be in grams (g) or kilograms (kg) and the volume can be in cubic centimeter (cm³) or liter (L) respectively.
It should be noted that cubic centimeter (cm³) and milliliter (mL) have the same value. Liter (L) and cubic decimeter (dm³) have the same value also.
Hence, the units for density can be Kg/L or Kg/dm³, g/mL or g/cm³
From the above, it can be noted that kg/L and g/mL are the only correct options provided.
The outermost shell is referred to as the __________ shell. the electrons in the outermost shell are also referred to as the ____________ electrons.
A golfer, standing on a fairway, hits a shot to a green that is elevated 7.67 m above the point where she is standing. if the ball leaves her club with a velocity of 38.0 m/s at an angle of 33.9 ° above the ground, find the time that the ball is in the air before it hits the green.
Final answer:
To find the time the golf ball is in the air before hitting the green, analyze the vertical component of the initial velocity to calculate the time of flight, which is around 3.44 seconds.
Explanation:
The time that the ball is in the air before it hits the green can be calculated using the vertical motion of the ball.
By analyzing the vertical component of the initial velocity, you can determine the time of flight using the equation for motion under gravity.
In this case, the time the ball is in the air is approximately 3.44 seconds.
