Answer:
The magnitude of applied force,parallel to the incline is 575.38 N and parallel to the floor is 605 N.
Explanation:
Given:
Mass of the piano 
= 190 kg
Inclined angle 
= 18 degree
Considering gravity, 
= 9.8 
And
Using, 
and 
<em>FBD diagram is attached with all the force acting on the floor and and the inclined. </em>
We have to find the magnitude of forces,when the man pushes it parallel to the incline and to the floor.
a.
When the man pushes it parallel to the incline.
Balancing the forces as 
.
⇒ 
⇒ 
⇒ Here it is negative as the force is acting downward.
⇒ Plugging the values of mass and angle .
⇒ 
⇒ 
N
b.
When the force is parallel to the floor.
⇒ 
⇒ 
⇒ Plugging the values.
⇒ 
⇒ 
N
So,
The magnitude of applied force in inclined direction is 575.38 Newton and parallel to the floor is 605 N.
Technically, we don't have the information needed to calculate the current,
because you haven't mentioned the units of the 3.5 .
Since the 3.5 is a resistance, we strongly suspect ... and we'll therefore
assume ... that the 3.5 has the units of ohms. Then . . .
Current = (voltage) / (resistance) = (1.5/3.5) = <em>3/7 of an Ampere</em>.
(429 mA, rounded)

Answer:
There would be tremendous earthquakes and tsunamis, followed by massive volcanism around the impact zone. The ozone layer would be destroyed. The oceans would turn acidic. The Sun would be blotted out, probably for decades.

We use a spectrometer to help us determine what stars and planets are made of by passing a light through various chemical elements, different spectral patterns are created. By matching those patterns up to patterns generated in a laboratory environment we can tell what the composition of a distant star or planet is.
