Answer:
weight will decrease
Explanation:
this is because mad stays the same no matter what so it was between this and weight increases
Answer:
Its weight will decrease.
Explanation:
just because
Conduction causes the ankle to gain thermal energy.
Cold from the ice pack is transferred to the ankle.
Heat from the ankle is transferred to the ice pack.
The answer is:
Heat from the ankle is transferred to the ice pack.
The explanation:
-when the ice pack a lower temp than the ankle , it is very cool.
- and the injured ankle has a high temp or heat
and we know that Q transfer from the object with high heat to the object with the low temp So,
Heat will transfer from the ankle to the ice pack.
When someone places an ice pack on an injured ankle is : ( D ) Heat from the ankle is transferred to the ice pack
Conduction is the transfer of heat energy from a higher temperature body to lower region or body. The temperature of the Ice pack is lower than the temperature of the ankle therefore we cannot say conduction caused the ice pack to lose thermal energy rather the heat from the ankle is transferred to the ice pack because the ankle has a higher temperature compared to the ice pack.
Hence we can conclude that When someone places an ice pack on an injured ankle is Heat from the ankle is transferred to the ice pack.

Answer:
r= 3.2 cm
Explanation:
Given that
I= 8.7 A
B= 5.4 x 10⁻⁵ T
μo=1.25664 x 10⁻⁶
We know that magnetic filed in wire at a distance r given as
By putting the values
r=0.032 m
r= 3.2 cm
The distance from a long straight wire at which the magnetic field equals the strength of Earth’s field, given a current of 8.7 A and Earth's field of 5.4 × 10−5 T, can be calculated using the formula for the magnetic field around a current-carrying wire. Substituting the given values, the answer is approximately 37.22 cm.
To solve this physics problem, we will use the formula for the magnetic field produced by a current carrying long, straight wire. The formula is: B = μI / (2πr), where 'B' is the magnetic field strength, 'μ' is the permeability of free space, 'I' is the current, and 'r' is the radial distance away from the wire.
In this case, Earth’s magnetic field, 'B', is given as 5.4 × 10−5 T, the current, 'I', is given as 8.7 A, and the permeability of free space, 'μ', is given as 1.25664 × 10−6 T · m/A. We need to find 'r', the distance away from the wire, and we want this answer in centimeters.
So, rearrange the formula to solve for 'r': r = μI / (2πB).
Substitute our known values into the equation: r = (1.25664 × 10−6 T · m/A × 8.7 A) / (2π × 5.4 × 10^-5 T). After calculating, we need to convert from meters to centimeters by multiplying by 100. The final answer is approximately 37.22 cm.
