Answer:

C.the moon at apogee coming between Earth and the sun along a straight line

Explanation:

As we know that Earth rotate about the sun in elliptical orbit as one of the planet.

While moon rotate about the Earth similarly as one of the satellite around it

now when moon, Sun and Earth all lie in the same line such that position of moon is between the positions of Sun and Earth then in this case the light coming from sun is totally bounded by the position of moon

This situation of moon is known as Solar Eclipse

so here during the motion if the moon at apogee coming between Earth and the sun along a straight line then it is the most likely cause of annular solar eclipse.

<span>C.the moon at apogee coming between Earth and the sun along a straight line

So, option C is your most accurate answer.

Hope this helps!

Lithium atoms split when they are blank with a stream of protons

lions [1.4K]

The answer is; bombarded

John Cockcroft and Ernest Walton split the lithium atom using accelerated protons. The atomic nuclei were split and the physicist observed alpha particles (two protons and two neutrons bound together into a particle identical to a helium-4 nucleus) as one of the products. The experiment also led to the discovery of the neutron and positron subatomic particles.

At the lowest point in a vertical dive (radius = 0.58 km), an airplane has a speed of 300 km/h which is not changing. Determine

murzikaleks [220]

Answer:

The centripetal acceleration is $a = 11.97 \ m/s^2$

Explanation:

From the question we are told that

The radius is $r = 0.58 \ km = 0.58 * 1000 = 580 \ m$

The speed is $v = 300\ km /hr = \frac{300 *1000}{1 * 3600 } = 83.33 \ m/s$

The centripetal acceleration of the pilot is mathematically represented as

$a = \frac{v^2 }{r}$

substituting values

$a = \frac{(83.33)^2 }{580}$

$a = 11.97 \ m/s^2$

never [62]

Answer:

Em₀ = 245 J

Explanation:

We can solve this problem with the concepts of energy conservation, we assume that there is no friction with the air.

Initial energy the highest point

Em₀ = U

Em₀ = m g h

The height can be found with trigonometry

The length of the pendulum is L and the length for the angle of 60 ° is L ’, therefore the height from the lowest point is

h = L - L’

cos θ = L ’/ L

L ’= L cos θ

h = L (1 - cos θ)

We replace

Em₀ = m g L (1- cos θ)

Let's calculate

Em₀ = 10 9.8 5.0 (1 - cos 60)

Em₀ = 245 J

Answer:

A The truck exerts greater force

Explanation:

During collision the truck exerts greater force due to its much larger mass coupled with the speed than the car exerts on it thereby damaging the car more
