Answer: 1.81m
Explanation:
Given the following:
Horizontal speed = 4m/s
Height of table = 1m
Taking the vertical component of the motion:
Using:
S = ut + 0.5 at^2
Where, S = height of table, a = acceleration due to gravity (9.8m/s^2), t = time and u = Initial Velocity in vertical direction = 0
1 = 0(t) + 0.5(9.8)t^2
1 = 4.9t^2
t^2 = 1 / 4.9
t^2 = 0.204081
t = sqrt(0.204081)
t = 0.452s
For Horizontal :
Gravitational acceleration is absent, therefore distance can be calculated using:
Distance = Velocity × time
Distance = 4m/s × 0.452s
Distance = 1.808 m
Distance = 1.81m

Answer:
Sublimation is defined as the direct transition of a substance from solid state to gaseous state. The latent heat of sublimation is the sum of heat required for conversion from solid to liquid and heat required for conversion from liquid to gas. As in sublimation solid substance directly goes to gaseous state therefore, it is very difficult to find the components of latent heat of sublimation. This is the issue which arises in determining latent heat of sublimation.
On the other hand, when substance is melted it physically goes from solid to liquid. One can easily measure the heat required for this conversion.
Final answer:
Latent heat determination challenges differ between substances that sublime and those that melt. Sublimation involves a solid-to-gas change, typically under low pressure, making it difficult to contain the gas and measure accurate energy changes. In contrast, melting transitions from solid to liquid, with challenges in accurately measuring temperature change and ensuring complete melting.
Explanation:
When determining the latent heat of substances, different issues can arise depending on if the substance sublimes or melts. Melting is a transition from a solid to a liquid state, while sublimation involves a transition directly from a solid to a gas state.
One issue that might arise would be managing the environmental conditions. Sublimation often happens at low pressure, and ensuring a consistent low-pressure environment can be challenging. Also, because the substance is transitioning directly to a gas, it may be more difficult to accurately measure the energy change as some gas may escape during the process.
For melting substances, the issues are different as one is transitioning from a solid to a liquid state, and it's typically measured at atmospheric pressure. Accuracy in measuring the temperature change and ensuring the entire substance has completely melted are potential challenges.

Answer:
398.3 m, 334.2 m
Explanation:
The magnitude of the displacement vector is
v = 520 m
And its direction is
measured as north of east.
The x-component of this vector is given by:
While the y-component is given by
Final answer:
The x-component of the displacement vector (east-west direction) is approximately 398 m and the y-component (north-south direction) is approximately 334 m.
Explanation:
Displacement vectors contain both magnitude and direction information. In the case of a displacement vector 520 m long, pointing 40 degrees North of East, we can break it down into x and y components using trigonometric functions, specifically cosine and sine.
For the x-component (east-west direction), we can use the cosine function because it gives us the adjacent side in a right triangle, which is the east-west direction in our case. Therefore, the x-component will be:
520 m * cos(40) = 398m (rounded to nearest unit).
For the y-component (north-south direction), we can use the sine function because it gives us the opposite side in a right triangle, which is the north-south direction in our case. Hence the y-component will be:
520 m * sin(40) = 334 m (rounded to nearest unit).
