Answer:
9ms^2
Explanation:
since ,Force=mass*acceleration
then, acceleration=force/mass
and, Force=90N
Mass=10pound
therefore, acceleration=90/10
=9ms^2
Answer:
She is likely to crash because her flight gradient is lesser than the flight gradient required gradient to avoid crashing
Explanation:
The given parameters are;
The required gradient of the plane Ashley is flying needs to reach in order to take off and not crash = 360 m/km
The initial elevation of the plane Ashley is flying = Sea level = 0 m
The goal Ashley intends to make = Elevation of 1000 m at 2.8 km. distance
∴ Ashley's goal = Traveling from sea level to 1000 m at 2.8 km horizontal distance
We have;
The gradient = Rate of change of elevation/(Horizontal distance)
Therefore;
The gradient of Ashley's flight = (1000 - 0)/(2.8 - 0) = 357.143 m/km
The gradient of Ashley's flight ≈ 357.143 m/km which is lesser than the required 360 m/km in order to take off and not crash, therefore, she will crash.
Material from the early solar system that was never transformed into a planet is now left over in space. After the planets formed, particles collided and created space debris.
Radiation pressure from the sun and the powerful solar wind both helped to expel the gas from the solar nebula. By the end of the Heavy Bombardment period, part of the residual debris had been removed from the nebula. The nebular hypothesis is the theory of planetary creation that is most widely accepted. According to this theory, the Solar System was created 4.6 billion years ago as a result of the gravitational collapse of a massive molecular cloud that stretched across several light-years.

' D ' is the only correct statement on the list.
Electromagnetic waves are capable of traveling through
many substances, and they're also capable of traveling
through vacuum. Mechanical waves can't travel in vacuum.
