STP stands for standard temperature and pressure. <span>The standard temperature is 273 K (0° Celsius or 32° Fahrenheit) and the standard pressure is 1 atm pressure. Also, at this condition 1 mole of a substance is equal to 22.4 L.Therefore, the first and the third options are the correct ones.</span>
Answer:
If a chord had notes with frequencies of 100, 1,000, and 6,000 Hz, the basilar membran would vibrate at multiple positions, with peaks at A, B, and C.
Explanation:
Momentum = 0.5 * 4 = 2
to conclude the man’s velocity after he throws the piece of equipment, divide
this number by the man’s mass.
v = 2/90
This is about 0.0222 m/s. To know if he can move 6 meters at velocity in
4minutes, use the following equation.
d = v * t, t = 4 * 60 = 240 s
d = 2/90 * 240 = 5⅓ meters.
This is ⅔ of a meter from the spaceship. To know the velocity that he must have
to move 6 meter, use the same equation.
6 = v * 240
v = 6/240
This is about 0.00416 m/s.
His final momentum = 90 * 6/240 = 2.25
To know the velocity of the package, divide this number by the mass of the
package.
v = 2.25/0.5 = 4.5 m/s
Answer:
b) one-third as great.
Explanation:
As we know that same heat is supplied in this experiment
so we will have
now we know that both are initially at same temperature
then their final temperatures are
now we have
so we have
so heat capacity of mystery metal is 1/3 times that of water
