As a rocket travels upward from earth, air resistance decreases along with the force of gravity. The rocket's mass also decrease

s as it uses up its fuel. If thrust remains the same, how do these factors affect the rocket's acceleration

Answer:

The decrease of these factors increases the acceleration.

Explanation:

Hi, the decrease of these factors increases the acceleration.

Air resistance is a force opposing the acceleration. So if it decreases, the acceleration increases, because the opposite forces decreases.

The same is applied to the force of gravity, since the rocket travels upward; gravity is also an opposite force.

Finally, if the mass decreases, it means that the rocket becomes lighter and the force acting on the smaller mass causes an increase in the acceleration.

A 7.3 cm diameter loop of wire is initially oriented so that its plane is perpendicular to a magnetic field of 0.61 T pointing u
kenny6666 [7]

Answer:

induced emf =  28.65 mV

Explanation:

given data

diameter = 7.3 cm

magnetic field = 0.61

time period = 0.13 s

to find out

magnitude of the induced emf

solution

we know radius is diameter / 2

radius = 7.3 / 2

radius = 3.65 m

so induced emf is dπ/dt  = Adb/dt

induced emf =  A × ΔB / Δt

induced emf =  πr² × ΔB / Δt

induced emf =  π (0..65)² × ( 0.61 - (-0.28))  / 0.13

induced emf =  0.0286538 V

so induced emf =  28.65 mV

Describe three physical changes that occur in nature?
Alex Ar [27]

Answer: Physical changes in nature could then be erosion in a mountain, the melting of snow, and a river freezing over from the cold. Since none of these changes affect the chemical composition of the mountain, the snow, or the river, they are physical changes.

Xavier is roller skating at 14 km/h and tosses a set of keys forward on the ground at 8 km/h. The speed of the keys relative to
Arturiano [62]

Answer:

22 km/h

Explanation:

Given that,

Speed of Xavier, v = 14 km/h

He tosses a set of keys forward on the ground at 8 km/h, v' = 8 km/h

We need to find the speed of the keys relative to the ground. Let it is V.

As both Xavier and the keys are moving in same diretion. The relative speed wrt ground is given by :

V = v+v'

V= 14 + 8

V = 22 km/h

So, the speed of the keys relative to the ground is 22 km/h.

Describe the two main ways that energy travels through the Sun.
ValentinkaMS [17]

Answer:

The energy are traveled through the sun in two ways that are:

  • By the radiation
  • By the convection

As, the energy are first traveled outward from the core of the sun and then it get entered in the zone of the radiation and this zone is known as radiative zone in the surface of the sun.In the radiation process some amount of the hydrogen particle are combined and then releases the energy. And the convection is the process of conversion of one form of energy to another form.
