Answer:
"12.4 g/mL" would be the right solution.
Explanation:
The given values are:
Mass of the object,
= 149.8 g
Volume of the object,
= 12.1 mL
Now,
The Density will be:
⇒ 
On substituting the given values in the above formula, we get
⇒ 
⇒ 
Answer:
15.7m/s
Explanation:
To solve this problem, we use the right motion equation.
Here, we have been given the height through which the ball drops;
Height of drop = 14.5m - 1.9m = 12.6m
The right motion equation is;
V² = U² + 2gh
V is the final velocity
U is the initial velocity = 0
g is the acceleration due to gravity = 9.8m/s²
h is the height
Now insert the parameters and solve;
V² = 0² + 2 x 9.8 x 12.6
V² = 246.96
V = √246.96 = 15.7m/s
Answer:
A) psychrometer
Explanation:
A psychrometer measures the relative humidity in the atmosphere not the wind.
A compass would work differently on the moon than the Earth because Earth's magnetic field is between 25,000 and 65,000 NanoTeslas. Whereas, the Moons magnetic field is about 2,500-6,500 and some parts of the moon have nonexistent magnetic fields.
Due to damming the water it will not flow as fast and since it wont flow as fast it will cause the water level to rise.
