Which sequence shpes the steps of the proces of science in an order in which they might occur?

ivanzaharov [21]

The steps of the process of science in an order in which they might occur

exploration >> hypothesis >> prediction >> experiment.

The correct option is D.

<h3>Explanation:</h3>

A series of sequential steps are included in the scientific method, which is how knowledge in the scientific field is acquired.
When a question arises from observing the natural world, a hypothesis is a predetermined explanation of the question.
Experimental and/or observational procedures must be used to test a hypothesis and determine whether it is true or false.

<h3>What are some fundamental scientific procedures?</h3>

When scientists conduct research and study, they use specific science process skills. The thinking processes that scientists, teachers, and students use when conducting science include observing, categorizing, communicating, measuring, inferring, and predicting.

A mass M tied to a light string is moving in a vertical circle. The tension in the string at the top is TT and TB at the bottom

natita [175]

Answer:

Explanation:

Tension provides centripetal force in the circular motion . In circular motion work done by force = torque x angle

torque is zero as , centripetal force passes through axis of rotation that is center.

So work done by centripetal force = 0

So work done by tension on M = 0

The gravitational attraction between a 20 kg cannonball and a 0.002 kg

Naya [18.7K]

Answer:

$2.966\times 10^{-11}\ N$

Explanation:

Given:

Mass of the cannonball (M) = 20 kg

Mass of the marble (m) = 0.002 kg

Distance between the cannonball and marble (d) = 0.30 m

Universal gravitational constant (G) = $6.674\times 10^{-11}\ m^3 kg^{-1} s^{-2}$

Now, we know that, the gravitational force (F) acting between two bodies of masses (m) and (M) separated by a distance (d) is given as:

$F=\dfrac{GMm}{d^2}$

Plug in the given values and solve for 'F'. This gives,

$F=\frac{(6.674\times 10^{-11}\ m^3 kg^{-1} s^{-2})\times (20\ kg)\times (0.002\ kg)}{(0.30\ m)^2}\\\\F=\frac{6.674\times 20\times 0.002\times 10^{-11}\ m^3 kg^{-1+2} s^{-2}}{0.09\ m^2}\\\\F=2.966\times 10^{-11}\ kg\cdot m\cdot s^{-2}\\\\F=2.966\times 10^{-11}\ N.........(1\ N = 1\ kg\cdot m\cdot s^{-2})$

The same force is experienced by both cannonball and marble.

Therefore, the gravitational force of the marble is $2.966\times 10^{-11}\ N$
