Answer:
Therefore the velocity of the proton is m/s towards east.
Explanation:
The mass of proton is m= kg.
q= C is the magnitude of the charge of a proton.
The earth's magnetic field is B= T toward north.
Let v be the velocity of the proton towards east.
The angle between the velocity of proton towards east and magnetic field towards north is .
We know that,
Now putting the all values
m/s
Therefore the velocity of the proton is m/s towards east.
To solve this problem it is necessary to apply the concepts related to conservation of the moment.
By definition for the particular case we have to,
Where,
Mass first skater
Speed of first skater
Velocity of second skater
Our values are given as,
Replacing in our equation and re-arrange to find
The mass from the second skater is 35.85Kg
Answer:
1.6 meters east
Explanation:
Note: Image attached.
As we can see on the data, Anita is further from the puddle than Nick. Additionally, the distances relatives to the center of the puddle allow us to now the lenght of the rope which is the sum of these two, 9.2 meters. We also know that the knot is at the middle of the rope, so it means it is at 4.6 meters of both Anita and Nick. Now what is next? Well, we now have everything we know. We have the distance between Anita and the puddle and we also know the distance between Anita and the knot (4.6 meters). We just need to subtract the distance to the knot from the distance to the puddle which is equal to 1,6 meters east direction.

Answer: 15000 J
Explanation:
Given ;
Temperature change, dθ = 10
Mass of substance, m = 5 kg
Specific heat capacity, C = 300 j/kg°C
Quantity of heat, Q required is obtained using the relation ;
Q = mCdθ
Q = 5kg * 300 j/kg°C * 10°C
Q = 5 * 300 J * 10
Q = 15000 J
