Answer:
θ=142.9°
Explanation:
d=1 *r
angle ϕ= 37.1°
the line connecting pebble and target should be tangent to a circle so
cos(180-ϕ-θ)=
=
∴ θ=180-ϕ-
θ= 180-37.1-0
θ=142.9°
The density will be 1.05
The mass will be 13.65
Answer:
Answer: Option (D) is the correct answer.
Explanation:
Before placing the spoon in a hot liquid, particles of spoon were closer to each other and vibrating at their respective positions.
But when the spoon is placed in a hot liquid then due to increase in temperature of spoon its particles gain kinetic energy. Therefore, they colloid more frequently.
Thus, we can conclude that switch the labels on the diagrams best explains how to correct Alana’s error.
Answer:
λ = 0.03 s⁻¹
Explanation:
The formula for decay constant can be used as follows:
where,
= ratio of remaining nuclei to the initial value of nuclei = 
= 0.167
t = time = 60 s
λ = decay constant = ?
Therefore,
<u>λ = 0.03 s⁻¹</u>
