If force is applied at 30 degree with the horizontal
then first we will find the components of force in two directions
now we can find normal force by balancing the forces in Y direction
now since block is moving with constant speed
so here forces along horizontal plane will be balanced also
Now the weight of the box is defined as
now plug in all values
Answer:
Potential difference across resistor will be 87.66 volt
Explanation:
We have given number of electrons
Charge on one electron
So total charge
Time is given t = 5 min
1 minute = 60 sec
So 5 minute = 5×60 = 300 sec
So current
Resistance is given R = 40 ohm
Sp from ohm's law potential difference across resistor v = iR = 2.1866×40 = 87.466 volt
Answer:
(0.25X+25)N
Explanation:
-let the weight of the box be X.
-Given that the the force needed is equal to one half the weight of the box plus 25N:
Hence, the total force needed is (0.25X+25)N
A small, rocky particle that moves through space and strikes a planet or moon is referred to as a meteorite. A meteorite is a substantial part of the wreckage from a root such as an asteroid including comet, It is described as a meteoroid before its collision. Meteorite's intensity can change from petite to remarkably big.
Answer: <u><em>2.03259656 × 10^8</em></u>
Explanation:
1.5 x 10 = 15
√(15) = <em>3.87</em>
<u><em>put this to the side until we sum everything up..</em></u>
3.5 × 10 = 35
35 ^ 5 = <em>52521875</em>
So, now lets sum it all up....
(3.87) x (52521875) = <u><em>203259656.25</em></u>
but in scientific notation it is: <u><em>2.03259656 × 10^8</em></u>
