Answer:
A ball is thrown in an arbitrary direction and a rocket moves through the sky after its engines have failed.
Explanation:
The concept applied is that of projectile motion which is the free fall for both then horizontal and vertical component of a constant velocity. it is also the motion of an object thrown under the influence of acceleration due to gravity.
The correct option are as follows ; A ball is thrown in an arbitrary direction and a rocket moves through the sky after its engines have failed.
For the first case ; A ball is thrown in an arbitrary direction ; after the ball must have been thrown, the projectile further moves in a curved path.
for the second case ; A rocket moves through the sky after its engines have failed ; the rocket also moves in a curved path under the influence of the acceleration due to gravity.
The strength of the electric and magnetic fields there is no physical "distance" of oscillation here. nothing is actually moving up and down if you draw light as a sinusoidal wave, the up and down motion is the strength of the EM fields cheers
Answer:increased pressure to increase solubility
Explanation:B on ed
<span>We know the change of thermal energy is proportional to the specific heat of the matter, its mass and the change of temperatures, according the following formula:
Q = C*m*(Tf-Ti)
where:
Q is the heat added or removed (in joules, J)
C is the specific heat of the matter, in our case air 1,000 J/(Kg*C)
m is the mass, in our case 50 kg of air
Tf is final temperature
Ti is initial temperature
then:
Q = 1000 * 50 * (30-20) = 500,000 Joules
That means that 500,000 joules need to be added to increase temperature of the room 10 ÂşC (from 20 to 30 ÂşC)</span>
Answer;
- the direction the wire moves in
- the direction of the magnetic field
Explanation;
The direction of an electric current is also the direction in which a positive charge would move.
The direction of flow of electric current in a current carrying conductor such as a wire depends on a number of factors. These factors includes; the direction the wire moves in; that is current will flow towards the direction of a given wire or conductor.\
Secondly, the direction of magnetic field determines the direction of flow of electric current; this can be explained by the idea of induced current; the direction of induced current depends on the direction of magnetic field according the Fleming,s right hand rule.
