Answer: The penetrating power of alpha rays, beta rays, and gamma rays varies greatly. Alpha particles can be blocked by a few pieces of paper. Beta particles pass through paper and Gamma rays are the most difficult to stop and require concrete, lead, or other heavy shielding to block them.
Answer:
1. T₁ = 500 N
2. T₂ = 866 N
Explanation:
Please see attached photo for the diagram.
Thus, we can obtain obtained the value of T₁ and T₂ as follow:
1. Determination of T₁
Angle θ = 30
Hypothenus = 100 kg
Opposite = T₁ =?
Sine θ = Opposite /Hypothenus
Sine 30 = T₁ / 100
Cross multiply
T₁ = 100 × Sine 30
T₁ = 100 × 0.5
T₁ = 50 Kg
Multiply by 10 to express in Newton
T₁ = 50 × 10
T₁ = 500 N
2. Determination of T₂
Angle θ = 60
Hypothenus = 100 kg
Opposite = T₂ = ?
Sine θ = Opposite /Hypothenus
Sine 60 = T₂ / 100
Cross multiply
T₂ = 100 × Sine 60
T₂ = 100 × 0.8660
T₂ = 86.6 Kg
Multiply by 10 to express in Newton
T₂ = 86.6 × 10
T₂ = 866 N
Answer:
Density
Explanation:
Each of the three liquids have different densities. Have you ever tried to mix oil and water? They don't mix because they have different densities.
The actual weight of the stone is 11 N. It is based on the Archimedes principles.
<h3>What is Archimedes principle?</h3>
- Archimedes principle states that the up thrust by water on an object is equal to the weight of water displaced.
- Upthrust by water on an object= actual weight of object - weight inside water
<h3>What is the actual weight of the object, if its weight inside water is 9N and weight of water displaced is 2N?</h3>
Actual weight= weight inside water+ weight of water displaced
= 9N + 2N = 11N
Thus, we can conclude that the actual weight of the object is 11N.
