The answer is A.
Copper is conductive hence Bernie could use the copper bowl to easily warm his food.
Copper is ductile hence Nicholas can easily bend his copper wire gauge
Copper is malleable hence can be easily shaped into a form hence used to make a bracelet for Matt’s mother.
Answer:
V₁ = 5.6 m/s
V₂ = 7.2 m/s
V₃ = 8.8 m/s
Explanation:
Average velocity: Average velocity can be defined as the ratio of the total displacement to the total time taken. The S.I unit of Average velocity is m/s.
For the first 2 s,
V₁ = Δd₁/t
Where V₁ = Average velocity for the first 2 s
Where Δd₁= distance, t = time
Δd₁ = 25.6-14.4 = 11.2 m t = 2 s
V₁ = 11.2/2
V₁ = 5.6 m/s
For the second 2 s,
V₂ =Δd₂/t
Where V₂ = average velocity for the second 2 s.
Δd₂= 40-25.6 = 14.4 m, t= 2 s
V₂ = 14.4/2
V₂ = 7.2 m/s
For the last 2 seconds,
V₃ =Δd₃/t
Where V₃ = average velocity for the last 2 s
where Δd₃ = 57.6- 40 = 17.6 m, t = 2 s
V₃ = 17.6/2
V₃ = 8.8 m/s.
Yes you are right but sometimes just because a number is bigger doesnt always make it so.
Answer:
The law of multiple proportions states that when two elements can combine in different ratios to form different compounds, the masses of the element combining with the fixed mass of another element result in whole number ratios. This shows that the law of multiple proportions is followed
Explanation:
Answer:
F = 339.23 N
Explanation:
Weight of a car, W = 1050 N
Initial velocity, u = 0
Final velocity, v = 42 m/s
Time, t = 13 s
The weight of an object is given by :
W = mg
g is the acceleration due to gravity
The force acting on car is :
So, the force acting on the car is 339.23 N.
