What does it mean if the moon is waxing and waning

Both verbs come from Olde English.
That's why everybody clearly understood their meaning until
a hundred years ago, but nobody understands them now.

"Waxing" = growing

For two weeks after the New Moon, it's growing toward Full.
First it's a waxing crescent for a week, then it's waxing gibbous.

"Waning" = shrinking

For two weeks after the Full Moon, it's shrinking toward New.
First it's waning gibbous for a week, then it's a waning crescent.

If The dimensions of a brick that weighs 25N are 0.19m x 0.07m x 0.095m. What pressure does the brick exert on the ground if it

valina [46]

1 newton per square meter = 1 pascal of pressure.

The largest face of the brick is (0.19 x 0.095) = .01805 square meter

25N/0.01805 = 1,385 newtons per square meter = 1,385 pascal = 1.385 kPa

We need to consider for this exercise the concept Drag Force and Torque. The equation of Drag force is

$F_D = c_D A \frac{\rho V^2}{2}$

Where,

F_D = Drag Force

$c_D$ = Drag coefficient

A = Area

$\rho$ = Density

V = Velocity

Our values are given by,

$c_D = 0.5$ (That is proper of a cone-shape)

$A = 9m^2$

$\rho = 1.2Kg/m^3$

$V = 6.5m/s$

Part A ) Replacing our values,

$F_D = 0.5*9*\frac{1.2*6.5^2}{2}$

$F_D = 114.075N$

Part B ) To find the torque we apply the equation as follow,

$\tau = F*d$

$\tau = (114.075N)(7)$

$\tau = 798.525N.m$

The muzzle velocity of a bullet fired from a new rifle is 100 m/s. Neglecting air resistance, at the end of one second a bullet

Burka [1]

Answer:

C. (100+4.9)m

Explanation:

u = 100m/s, t = 1 sec, g = 9.8m/s^2

s = ut + 1/2gt^2

s = 100×1 + 1/2×9.8×1^2 = 100+4.9

s = (100+4.9)m

Suppose that the centripetal force acting on an object in circular motion were doubled to a new value, and the object remained i

Lilit [14]

Explanation:

Centripetal force is mass times centripetal acceleration:

F = m v² / r

If force is doubled while mass and radius are held constant, then velocity will increase.

2F = m u² / r

2 m v² / r = m u² / r

2 v² = u²

u = v√2

So the velocity increases by a factor of √2.

Calculate the acceleration of a bus that speed up from 20ms-1 to 40ms-1 in 8 seconds?

Anastaziya [24]

Answer:

2.5 ms^-2

Explanation:

acceleration

= (final velocity - initial velocity)/time

= [(40m/s) - (20m/s)]/8s

= (20m/s)/8s

= 5/2 m/s²

= 2.5 m/s²

= 2.5 ms^-2
