(a) To find the magnitude of the torque on the loop, we can use the formula:
torque = μ × B × A × sin(θ) where μ is the magnetic moment of the loop, B is the magnetic field magnitude, A is the area of the loop, and θ is the angle between the magnetic field and the plane of the loop.
In this case, we don't have the magnetic moment (μ) provided.
However, the formula demonstrates that the torque depends on the angle between the magnetic field and the plane of the loop.
With the given values, the torque can be calculated as:
torque = μ × 4T × 5m² × sin(30°)
torque = μ × 4T × 5m² × 0.5
torque = 10μTm²
The magnitude of the torque on the loop is 10μTm², where μ represents the magnetic moment of the loop.
(b) The net magnetic force on the loop is zero. In a uniform magnetic field, the forces on the opposite sides of the loop cancel each other out, resulting in no net magnetic force.

An 80 kg skier stands at the top of a 40-meter slope. She then skis down the slope. What is her approximate speed at the bottom of the slope if friction is negligible and her kinetic energy is 31360 J?
Thank you for that information. If we know her mass and kinetic energy, then we don't need any of that other business about the height of the slope, her skiing ability, the friction of the snow, what she uses to wax her skis, the color of her parka, or what she had for lunch at the chalet. The mass and kinetic energy are enough to answer the question.
Kinetic Energy = (1/2) · (mass) · (speed)²
31,360 J = (1/2) · (80 kg) · (speed)²
speed² = (31,360 J) / (40 kg)
speed² = 784 m²/s²
speed = 28 m/s

Una pelota de golf se suelta desde el reposo del techo de un edificio muy alto. Despreciando la resistencia del aire, calcule (a) la posicion y (b) la velocidad de la pelota despues de 1s, 2s y 3s.
Answer:
a) y = y₀ - 4.9, v = -9.8 m / s, b) y =y₀ - 19.6, v = - 19 m / s
c) y =y₀ - 44.1, v = - 29.4 m / s
Explanation:
To solve this exercise let us use the kinematic relations
y =y₀ + v₀ t - ½ g t²
v = v₀ - g t
They indicate that the body is released therefore the initial velocity is zero v₀ = 0
y = y₀ - ½ g t²
v = - gt
a) the position and velocity for t = 1s
y = y₀ - ½ 9.8 12
y = y₀ - 4.9
v = - 9.8 1
v = -9.8 m / s
the negative sign indicates that the velocity is directed downwards
b) t = 2 s
y =y₀ - ½ 9.8 2 2
y =y₀ - 19.6
v = - 9.8 2
v = - 19 m / s
c) t = 3 s
y = y₀ - ½ 9.8 3 2
y =y₀ - 44.1
v = - 9.8 3
v = - 29.4 m / s

Which of the following statements is correct about air temperature?
1. When air temperature is higher, the weather is warmer.
2. Warm air falls to the ground.
3. Freezing air temperatures increase the chances of rain.
4. When air temperature is higher, the weather is colder.
Explanation:
Warm air falls to the ground
The statement that is correct about air temperature is when the air temperature is higher, the weather is warmer. The correct option is 1.
What is air temperature?A measurement of the air's heat or cold is its temperature. It is the weather parameter that is most frequently measured.
The kinetic energy, or energy of motion, of the gases that make up air, is more explicitly described by temperature. The temperature rises as gas molecules move more swiftly.
Surface temperatures are typically hotter than air temperatures. Parking your car in the sun is an illustration of this. The air inside the car will be fairly close to the outside air temperature and you may leave the windows down and yet have excellent ventilation.
Therefore, the correct option is 1. When the air temperature is higher, the weather is warmer.

Question 5: Which object traveled at a faster speed? (Make sure to show your
work!!)
Object A: 65 miles in 13 minutes
Object B: 125 miles in 25 minutes
Answer: objects A and B have the same speed.
Explanation:
Speed = distance divided by time.
Object A: 65 miles in 13 minutes
Speed (A) = 65 miles divided by 13 minutes
Speed (A) = 5 miles per minute
Object B: 125 miles in 25 minutes
Speed (B) = 125 miles divided by 25 minutes
Speed (B) = 5 miles per minute
Thus, objects A and B have the same speed.

Answer:
Mass, in physics, quantitative measure of inertia, a fundamental property of all matter. It is, in effect, the resistance that a body of matter offers to a change in its speed or position upon the application of a force. The greater the mass of a body, the smaller the change produced by an applied force.

A dog runs down his driveway with an initial speed of 5.0 m/s for 8 seconds then uniformly increases his speed to 10 m/s in 5 seconds, how long is the driveway? SHOW WORK
Answer:
to find the displacement, or delta x (change in position) on a velocity graph, you can find the area under the line on the graph: between 1 and 8 seconds, the dog was going at 5m/s, so 5m/s x 8s=40m, for the second part, you have to find the area of both a triangle and a rectangle, so the rectangle would be 5m/s x 5s=25m and the area under the triangle would be (5m/s x 5s)/2=25m/2=12.5m -you divide by 2 because it's a triangle
-afterwards, you would add the area of the 2 sections together, so 40m+25m+12.5m=77.5m

PLEASE MARK ME BRAINLIEST, PLEASEExplain the advantages and disadvantages of having a racecar with a large mass in reference to Newton’s 1st law of motion. Use the term inertia in your answer.
Answer:
read the explanation
Explanation:
My answer to research question one is a car with a higher mass has more inertia than a car with a lower mass. A car with a higher mass needs more force to move than a car with a lower mass. The advantage of a car with greater mass is that it takes less impact when crash happens and has more protection.
The advantage of a race car with large mass is that it will continue moving without stopping once it is already in motion.
The disadvantage of a race car with large mass is that it will be difficult to get it start moving.
The Newton's first law of motion states that, an object in a state of rest or uniform motion in a straight line will continue in that form unless it is acted upon by an external force.
This first law is also known as law of inertia because it depends on mass of the object.
Inertia is reluctance of an object to move or stop moving once it is in motion.
Thus, the advantage of a race car with large mass is that it will continue moving without stopping once it is already in motion.
The disadvantage of a race car with large mass is that it will be difficult to get it start moving.
