Physics

A horizontal spring is lying on a frictionless surface. One end of the spring is attached to a wall, and the other end is connected to a movable object. The spring and object are compressed by $0.065 \mathrm{m},$ released from rest, and subsequently oscillate back and forth with an angular frequency of 11.3 $\mathrm{rad} / \mathrm{s}$ . What is the speed of the object at the instant when the spring is stretched by 0.048 $\mathrm{m}$ relative to its unstrained length?

Precious metals and gems are measured in troy weights in the English system:
$$\begin{aligned} 24 \text { grains } &=1 \text { pennyweight (exact) } \\ 20 \text { pennyweight } &=1 \text { troy ounce (exact) } \\ 12 \text { troy ounces } &=1 \text { troy pound (exact) } \\ 1 \operatorname{grain} &=0.0648 \mathrm{g} \\ 1 \text { carat } &=0.200 \mathrm{g} \end{aligned}$$
a. The most common English unit of mass is the pound avoirdupois. What is 1 troy pound in kilograms and in pounds?
b. What is the mass of a troy ounce of gold in grams and in carats?
c. The density of gold is 19.3 $\mathrm{g} / \mathrm{cm}^{3} .$ What is the volume of a troy pound of gold?

A solution contains a mixture of 30 mL of 0.3 M HNO3 and 60 mL of 0.8 M Ba(OH)2. Calculate the pH of this solution.
Hint 1: 2 HNO3(aq) + Ba(OH)2(aq) → 2 H2O(l) + Ba(NO3)2(aq)
Hint 2: HNO3 is a strong acid. Ba(OH)2 is a strong base
Hint 3: M = mol/L
