Answer:
am pretty sure u have to measure like my name is Justin am cracked at fortnite my Guy
Answer:
B, i think.
Explanation:
Calculate the number of moles of solute present.
Moles of Na0H =15.0g Na0H x 1 molNa0H over 40.00g Na0H= 0.375 mol Na0H.
Calculate the liters of solution present.
volume=225mL x iL over 1000mL = 0.225 L soln
Divide the number of moles of solute by the number of liters of solution.
Molarity= 0.375mol over 0.225L =1.67 mol/L
Answer:
The correct answer is d Both the observer's are correct
Explanation:
We know by postulates of relativity that laws of physics are same in different inertial frames.
Thus for each of the frames they make observations related to their frames and since the observations are true for their individual frames they both are correct. But when we compare the two frames we need to use transformation equations to compare both the results.
Answer:
A few of the positive particles aimed at a gold foil seemed to bounce back.
Explanation:
Answer:
Power, P = 722.96 watts
Explanation:
It is given that,
Voltage, V = 120 V
Length of nichrome wire, l = 8.9 m
Diameter of wire, d = 0.86 mm
Radius of wire, r = 0.43 mm = 0.00043 m
Resistivity of wire,
We need to find the power drawn by this heater. Power is given by :
And,
P = 722.96 watts
So, the power drawn by this heater element is 722.96 watts. Hence, this is the required solution.
