Answer: 40m
Explanation: Distance is a function of speed/ velocity and time.
From the question the velocity along the z axis is given as 20 m/s at t = 0 secs We were ask to calculate the distance travelled when t = 2secs.
Recall that,
Velocity = distance travelled / time
Since we're calculating for distance we make it subject of formula;
Distance travelled = velocity * time
= 20m/s * 2s
= 40meter.
Answer:
The amount of energy released by the earthquake in joules is 4.4×10^12 J.
Explanation:
As, we have given the magnitude,
M = 2/3 Log E/Eo
where E is the amount of energy released by the earthquake in joules and Eo=10^4.4 is the assigned minimal measure released by an earthquake.
As, the magnitude is given which is 5.5 then put it in the above equation,
5.5 = 2/3 Log E/Eo
Log E/Eo = 5.5×3 / 2
Log E/Eo = 8.25
Now, we will find the amount of energy released by an earthquake:
Log E/Eo = 8.25
Taking antilog,
E/Eo = 10^8.25
But Eo is given which is Eo = 10^4.4
E/(10^4.4) = 10^8.25
E = 10^8.25 × 10^4.4
E = 4.4×10^12 J.
Since the total pressure of each gas is the sum of the partial pressures of all the individual gases, the vapor pressure of oxygen is 1.3 atm.
From Dalton's law of partial pressure, the total pressure is the sum of the individual partial pressures of the gases;
PT = PA + PB + PC + --------
Given that;
Vapor pressure of oxygen = 0.2 atm
Total pressure = 1.5 atm
Vapor pressure of oxygen = ?
Partial pressure of oxygen = 1.5 atm - 0.2 atm = 1.3 atm
The vapor pressure of oxygen is 1.3 atm.

Answer:
17086
Explanation:
We are given that
Weight=5 kg
Distance of elbow from the weight=d=35 cm=
1 m=100 cm
g=
Work done each time on the weight=
20% means 0.20 of food energy=Work done each time on weight
Total work done in each time=
1 food calorie=4186 J
350 food calories=
Number of lift needed=
Hence, you must do 17086 arm raises to work off 350 food calories.
