The asnwer is in the picture
1) Horizontal velocity, Vx
Vx is constant and equal to 5.0 m/s
The graph Vx(t) = 5.0 m/s is a horizontal line (parallel to the horizontal t-axis). that intercepts the vertical-axis at 5.0 and runs from t = 0 to t = 2.
2) Vertical velocity, Vy
Vy = gt = 10t
d = at^2 / 2 => tmax = √(2d / a) = √(2*20m/10m/s^2) = 2 s
Graph Vy is an inclined line with slope 10 m/s^2, that runs from t =0 to t = 2 s, and passes through the points (0,0), (1,10), and (2,20).
Answer:
Option d
Explanation:
Interference is the phenomenon in which two or more waves having the same frequency combines or cancel out each other to form a resulting wave with the amplitude equals the sum of the amplitudes of the waves that are combined.
Thus it is clear that the particle with the wave nature can produce interference pattern. Hence, electron, light, sound, all of these produces interference pattern when directed towards the slits that are suitably spaced.
Answer:
increases by a factor of 4.
Explanation:
The power dissipated through a resistor is I2RI2R
Current=IResistance=RPower=(current)2×(resistance)=I2RIf we double the current, P=(2I)2R=4I2RCurrent=IResistance=RPower=(current)2×(resistance)=I2RIf we double the current, P=(2I)2R=4I2R
Thus, doubling the current increases the power dissipated through a resistor by a factor of four.
