Answer
given,
mass of jogger = 67 kg
speed in east direction = 2.3 m/s
mass of jogger 2 = 70 Kg
speed = 1.3 m/s in 61 ° north of east.
jogger one

now
P = P₁ + P₂
magnitude




the angle is
north of east
Answer:
the answer is 0.5m/s..... see the image for explanation
Answer:
Explanation:
Magnetic field due to a long current carrying conductor
μ₀ / 4π x 2i / r ( i = current , r = distance of point from wire )
= 10⁻⁷ x 2 x 120 / 6.4 ( i = 120 A , r = 6.4m )
= 37.5 x 10⁻⁷ T .
= 3. 75 X 10⁻⁶ T .
= 3.75 µT.
b )
The direction of this field will be horizontal hence it will affect magnetic needle.
In order for the heat to be transferred from the body X to the body Y via conduction, there must be a difference in temperature of body X with respect to body Y. Body X must have a higher temperature than body Y. This process continues until both bodies arrive at thermal equilibrium, meaning they both have the same temperature.
The words best describe the archer's results are The correct option is A.
<h3>What is accuracy?</h3>
When in an experiment, a value is measured 5 times, then if the values measured are same for most of the time or like three times out of five, it said to be accurate. The phenomenon is accuracy.
Precision is about comparing the values to each other then find them near to each other.
Given is an archer's targets on the target board.
Accuracy compares the experimental value to the theoretical value (desired target)
So, when all the values are close to each other but not nearest to the theoretical value, then it is said to be precise but not accurate.
Thus, the correct option is A.
