Answer:
Avoid using tweezers to remove the stinger, since squeezing it may release more venom. Wash the area of the bite with soap and water. Place a cold compress or ice pack on the area for about 10 minutes at a time to help reduce pain and swelling
Explanation:
so basically B, i hope this helps and its not too late!
First, remove the stinger with mild force and wash the area thoroughly with soaps. Apply cold compress or ice packs to avoid swellings. Hence, option B is correct.
What is histamines?Histamines are chemical substances in our body generating allergic action on skin. When some allergens or stimuli are exposed with our skin, histamine is produced.
Similarly if an insect with stinger bite on our skin, histamine is produced and allergic reactions occurs in our body. The bitten area has to be washed for minutes with soap. If any stinger persist on skin remove it.
Cold compress or ice packs are very helpful if the skin starts to swell. If any pain occurs, lower doses of pain killers can be taken. If necessary antihistamines have to be taken.

Answer:
b) 18 m/s is the correct answer.
Explanation:
initial velocity(u) = 30m/s
acceleration(a) = -4m/s²
time(t) = 3 seconds
final velocity(v) = ?
using the formula,
a = (v-u)/t
or, -4 = (v-30)/3
or, -12 = v-30
or, v = -12+30
so, v = 18 m/s
A ball that weighs 20 N has 40 J of potential energy relative to the ground. What is its height?
Answer:
2m, or 2 meters.
Acceleration is always measured in meters per second squared. Why is acceleration not measured in meters per second like speed? Explain.
Answer:
Because 'distance per second' is a velocity, not an acceleration.
Explanation:
Because 'distance per second' is a velocity, not an acceleration. For example, at 1 m/s an object is travelling a distance of 1 metre every second. But a rate of acceleration is a steady increase in velocity. So at 1 m/s^2, an object's velocity is increasing by 1 m/s every second.
How much work is required to move a 1 nC charge from an electric potential of 0 V to a potential of 18V?
a) 56 µJ
b) No work is required by an external force because this is the natural movement of the charge.
c) 18 J
d) 56 MJ
e) 18GJ
f) 18 nJ
The work required to move a 1 nC charge from an electric potential of 0 V to a potential of 18 V is 18 nJ (Option f).
When moving a charge in an electric field, the work done can be calculated using the formula W = qΔV, where W is the work done, q is the charge, and ΔV is the change in electric potential.
In this case, the charge is[tex]0.36V * 1600 kg/m^3 = 0.36 * 0.088 m^3 * 1600 kg/m^3 = 88 kg.[/tex]) and the change in potential is 18 V. Plugging these values into the formula, we get[tex]W = (1 × 10^-9 C)(18 V) = 18 × 10^-9 J = 18 nJ.[/tex]
Therefore, the correct answer is option f. No other options accurately represent the work required to move the charge in this scenario.

Standing waves are set up on two strings fixed at each end, as shown in the drawing. The two strings have the same tension and mass per unit length, but they differ in length by 0.58 cm. The waves on the shorter string propagate with a speed of 41.9 m/s, and the fundamental frequency of the shorter string is 225 Hz. Determine the beat frequency produced by the two standing waves.
The beat frequency produced by the two standing waves is 13 Hz.
The wavelength of the shorter stringThe wavelength of the shorter string is calculated as follows;

Answer in units of a.
Part 2
Find the y-coordinate of the center of gravity
(as a multiple of a).
Answer in units of a.
a) The x-coordinate of the center of gravity is [tex]\frac{19}{18}\cdot a[/tex].
b) The y-coordinate of the center of gravity is [tex]\frac{19}{18}\cdot a[/tex].
Determination of the coordinates of the center of gravity
Let suppose that each square has an uniform density, the coordinates of the center of gravity of each square with respect to the origin are, respectively:
[tex]\vec r_{1} = (0.5\cdot a, 0.5\cdot a)[/tex]
[tex]\vec r_{2} = (1.5\cdot a, 0.5\cdot a)[/tex]
[tex]\vec r_{3} = (0.5\cdot a, 1.5\cdot a)[/tex]
[tex]\vec r_{4} = (1.5\cdot a, 1.5\cdot a)[/tex]
The center of gravity of the entire system is found by applying definition of weighted averages:
[tex]\vec r_{cg} = \frac{W_{1}\cdot \vec r_{1}+W_{2}\cdot \vec r_{2}+W_{3}\cdot \vec r_{3}+W_{4}\cdot \vec r_{4}}{W_{1}+W_{2}+W_{3}+W_{4}}[/tex]
Where [tex]W_{1}[/tex], [tex]W_{2}[/tex], [tex]W_{3}[/tex] and [tex]W_{4}[/tex] are weights of the each square, in newtons.
Now we proceed the coordinates of the center of gravity of the entire system:
[tex]\vec r_{cg} = \frac{(50\,N)\cdot (0.5\cdot a, 0.5\cdot a) + (30\,N)\cdot (1.5\cdot a, 0.5\cdot a)+(30\,N)\cdot (0.5\cdot a, 1.5\cdot a)+(70\,N)\cdot (1.5\cdot a, 1.5\cdot a)}{50\,N+30\,N+30\,N+70\,N}[/tex]
[tex]\vec r_{cg} = \frac{5}{18}\cdot (0.5\cdot a, 0.5\cdot a) +\frac{1}{6}\cdot (1.5\cdot a, 0.5\cdot a) +\frac{1}{6}\cdot (0.5\cdot a, 1.5\cdot a) + \frac{7}{18}\cdot (1.5\cdot a, 1.5\cdot a)[/tex]
[tex]\vec r_{cg} = \left(\frac{19}{18}\cdot a, \frac{19}{18}\cdot a \right)[/tex] [tex]\blacksquare[/tex]
a) The x-coordinate of the center of gravity is [tex]\frac{19}{18}\cdot a[/tex]. [tex]\blacksquare[/tex]
