i think the answer is B police siren.
Answer:
Explanation:
Using the equation of motion v² = u²+2as
v is the final velocity = 40m/s
u is the iniyail velocity 0m/s
a is the acceleration
s is the displacement
Substituting in the formula;
40² = 0²+2a(50)
1600 = 100a
Divide both sides by 100
100a/100 = 1600/100
a = 16
Hence the car acceleration is 16m/s²
Answer:
The drum struck with a lot of energy would be louder than the drum struck with little energy because there is a harder impact on it
Explanation:
For the resistor closest to the battery, drawn vertical in the diagram, I = 8 A and P = 320 watts.
Also, the battery voltage is 40 V.
There isn't enough information included in the picture to fill in any of the missing items for the other two resistors.
Answer: t-trees?
i couldn't find anything on this topic but the only thing i could think of was trees, maybe if you go to a history website you can find a answer there :)
