Neutral reaction is the reaction that occurs when an acid cancels with a base
Answer:
a)Change in the speed = 1.41 m/s
b)The final speed will be 3.11 m/s
Explanation:
Given that
Acceleration ,a= 4.7 x 10⁻³ m/s²
a)
We know that
v= u + a t
v=final speed ,u=initial speed
t= time ,a= acceleration
Change in the speed
v- u = a t
t= 5 min = 5 x 60 s = 300 s
v- u = 4.7 x 10⁻³ x 5 x 60 m/s
v-u = 1.41 m/s
Change in the speed = 1.41 m/s
b)
Given that
u= 1.7 m/s
v-u = 1.41 m/s
v= 1.7 + 1.41 m/s
v=3.11 m/s
The final speed will be 3.11 m/s
Answer:
E.)none of the above
Explanation:
Elastic energy = kinetic energy
½ kx² = ½ mv²
v = x √(k / m)
v = 0.2 m √(20 N/m / 2 kg)
v = 0.632 m/s
Time to travel 2.0 m:
t = (2.0 m) / (0.632 m/s)
t = 3.16 s
V = I R
12 = I x 4
I = 12 ÷ 4 = 3 A
Answer:B The red ball has greater kinetic energy because it has greater mass
