Answer:
The density of the wood is
ρ₂ = 1.21 g / cm³
Explanation:
The block measures
V₁ = 10.0 cm * 4.0 cm * 2.0 cm
V₁ = 80 cm³
Now the block measures under the water getting just the face below as 1.65 cm
V₂ = 10.0 cm * 4.0 cm * 1.65 cm
V₂ = 66 cm³
So to determine the density knowing the mass are the same as the weight
ρ₁ * V₁ = ρ₂ * V₂
Using the density of the water as a
ρ₁ = 1 g / cm ³
1 g / cm³ * 80 cm ³ = ρ₂ * 66 cm³
ρ₂ = 1.21 g / cm³
Answer:
Also 0
Explanation:
Since average speed of an object is that object's displacement over a unit of time, when an average speed is 0, its displacement over a unit of time must also be 0. When an average speed is not 0, then its displacement over a unit of time is also not 0 for that interval.
Answer:
<h3>The answer is 4.29 m/s²</h3>
Explanation:
The acceleration of an object given it's velocity and time taken acting on it can be found by using the formula
From the question
velocity = 30 m/s
time = 7 s
We have
We have the final answer as
<h3>4.29 m/s²</h3>
Hope this helps you
Answer:
A. Technician A only
Explanation:
A "chirping" noise is heard while the vehicle is moving forward, but stops when the brakes are applied. Technician A says that the noise is likely caused by the disc brake pad wear sensors. Technician B says the noise is likely a wheel bearing because the noise stops when the brakes are applied. In the given scenario <em>technician A is correct.</em>
