Answer: A lunar eclipse is when the Earth casts a shadow on the moon.

Explanation:Eclipses and transference are astronomical circumstances where a celestial body partially or covers the different celestial objects. A solar eclipse happens when the New Moon moves between Earth and the Sun while a lunar eclipse occurs when Earth casts a shadow on the Full Moon.

If im not wrong lunar eclipse is when the Earth, moln and sun all line up, leaving the Earth in the middle. You can recheck later.

How is the electrostatic force affected when the magnitude of a charge is doubled?

BaLLatris [955]

The magnitude of the electrostatic force between two charges is given by:
$F=k_e \frac{q_1 q_2}{r^2}$
where
ke is the Coulomb's constant
q1 and q2 are the two charges
r is the separation between the two charges

We can see that the magnitude of the force is directly proportional to the charges. This means that when one of the charges is doubled, the magnitude of the electrostatic force will double as well, so the correct answer is
A) <span>The magnitude of the electrostatic force doubles</span>

After landing on an unfamiliar planet, a space explorer constructs a simple pendulum of length 54.0 cm. The explorer finds that

Natasha2012 [34]

Answer:

g = 11.2 m/s²

Explanation:

First, we will calculate the time period of the pendulum:

$T = \frac{t}{n}$

where,

T = Time period = ?

t = time taken = 135 s

n = no. of swings in given time = 98

Therefore,

$T = \frac{135\ s}{98}$

T = 1.38 s

Now, we utilize the second formula for the time period of the simple pendulum, given as follows:

$T = 2\pi \sqrt{\frac{l}{g}}$

where,

l = length of pendulum = 54 cm = 0.54 m

g = acceleration due to gravity on the planet = ?

Therefore,

$(1.38\ s)^2 = 4\pi^2(\frac{0.54\ m}{g} )\\\\g = \frac{4\pi^2(0.54\ m)}{(1.38\ s)^2}$

If you were trying to kill a fish with a spear, would you aim where you see the fish

34kurt

No, you would aim slightly above, because when you throw the spear and it travels through the air it will fall slightly downwards by the time it reaches the fish.

Two forces of 6 lbs and 8 lbs act on an object. If these two forces form an angle of 60, then find the magnitude of the resulta

yawa3891 [41]

Answer:

The magnitude of Resultant force is F = 7.21-lbs

Explanation:

Two forces acting on an object which are named as F1 and F2.

The angle formed by the forces are 60-degrees

F1 = 6-lbs , F2 = 8-lbs

theeta = 60°

F = √F1²+F2²-2(F1)(F2)cos(theeta)

F = √(6)²+(8)²-2(6)(8)cos(60)

F = √36+64-(96)cos(60)

F = 7.21-lbs

where,

F1 = magnitude of force 1

F2 = magnitude of force 2

theeta = angle formed by forces
