In projectile mtion, what is the x-component of the initial velocity? if V= Vi = 100 m/s and the angle with horizontal axis Θ = 60 degrees
Answers
Answer:
???????????????????????
Explanation:
The x - component of the initial velocity is given as:
Ux = Vi cos theta
Ux = 100cos 60
Ux = 50m/s

There are two ways to make the statement true:
#1). Exchange the places of the words "Opposite" and "like".
#2). Exchange the places of the words "repel" and "attract".
Either ONE of these changes will make the statement true.
Doing BOTH of these changes will leave it false.
Answer:
False. Opposite electric charges will attract, and like charges will repel.

Answer:
87.5 mi/hr
Explanation:
The formula is A=Vf-Vi / t.
Final answer:
The final speed of the car after 5.0 seconds, given a starting speed of 50 mi/hr and an acceleration of 7.5 mi/hr/s, would be 87.5 mi/hr.
Explanation:
This problem involves calculating the final speed of a moving object given its initial speed, acceleration and time. Acceleration is defined as the change in velocity divided by the time taken(s). Given that the car accelerates from 0 to 60 mi/hr in 8 seconds, it means its acceleration is (60mi/hr - 0mi/hr) / 8s = 7.5 mi/hr/s. Now, if the car's starting speed were 50mi/hr, its final speed after 5.0 seconds would be calculating using the formula Final Speed = Initial Speed + (Acceleration * Time). Plugging in our values we get Final Speed = 50mi/hr + 7.5mi/hr/s * 5s = 87.5 mi/hr.

i really hope that this helps you a lot.
Final answer:
The correct answer is D. Protostar.
Nuclear fusion in a star's lifecycle begins during the protostar stage. This is when the temperature and pressure of the protostar ignite nuclear fusion, transitioning into a main sequence star.
Explanation:
In the life cycle of a star, nuclear fusion begins when the star has reached the protostar stage. The initial stage in the development of a star is the nebula, which is a cloud of dust and gas. Over time, the nebula's materials collapse under gravity to form a hot core known as a protostar.
When the protostar's temperature and pressure rises, it triggers nuclear fusion and the star begins turning hydrogen into helium.
This marks the transition from a protostar to a main sequence star, which is the stage of stable nuclear fusion.

A positive charge is placed in an electric field that points west. the direction of the force on the positive particle point toward the west.
What is an electric charge?
Due to the physical characteristic of electric charge, charged material experiences a force when it is exposed to an electromagnetic field. Electric charges can be positive or negative (commonly carried by protons and electrons respectively). While like charges repel one another, opposite charges attract. If an object has no net charge, we refer to it as neutral.
The charge on one electron is -1.6 ×10⁻¹⁹ coulomb.
As given in the problem statement when a positive charge is placed in an electric field that points west. the direction of the force on the positive particle will also point toward the west because for a positively charged
particle the direction of the electric field is the same as the force.
Thus, a positive charge is introduced into a westward-pointing electric field. the force acting on the positive particle points westward
