<span>To answer this question, the equation that we will be using is:
y = A cos bx + c
where A = amplitude, b = 2 pi/Period, Period = 12 hrs, c = midline,
x = t and y = f(t)
A = 1/2 (Xmax - Xmin)
12 - 2 / 2 = 10/2 = 5
b = 2 pi / 12 = pi/6
c = 1/2 (Xmax + Xmin)
12+2/2 = 7
answer: f(t) = 5 cos pi/6 t + 7 </span>
Answer:
O larger than the object and real
Explanation:
As we know by the formula of mirror

here we know that

so we have

so we have

so magnification is given as


so here we have

so image will be larger than object and real
<span>g = GMe/Re^2, where Re = Radius of earth (6360km), G = 6.67x10^-11 Nm^2/kg^2, and Me = Mass of earth. On the earth's surface, g = 9.81 m/s^2, so the radius of your orbit is:
R = Re * sqrt (9.81 m/s^2 / 9.00 m/s^2) = 6640km
here, the speed of the satellite is:
v = sqrt(R*9.00m/s^2) = 7730 m/s
the time it would take the satellite to complete one full rotation is:
T = 2*pi*R/v = 5397 s * 1h/3600s = 1.50 h
Hope it help i know it's long and may be confusing but if you have any more questions regarding this topic just hmu! :)</span>
<u>Answer:</u>
<em>The shear modulus of the cube material is
.
</em>
<u>Explanation:</u>
<em>Given that shearing force applied F = 1500 N </em>
<em>Displacement produced x = 0.1 cm=0.001 m </em>
<em>side of the cube =20 cm = 0.2 m
</em>
Since the object is a cube the upper surface is a square and it is on this surface the shearing
force is applied
<em>area of the upper surface
</em>
<em>shear strain = tan θ =
</em>
<em>shearing stress =
</em>
<em>modulus of rigidity η
</em>
