Answer:
1)m=89.01 g
2)V(max) = 97.3 cm/s
Explanation:
Given that
K= 15 N/m
The maximum amplitude ,A=7.5 cm = 0.075 m
Given that 31 oscillations in 15 seconds ,this means that frequency f
f=\dfrac{31}{15}
f=2.066 Hz
lets take mass of the ball = m kg
m=0.08901 kg
m=89.01 g
The maximum speed
V(max)= ω x A
ω = 2π f= 2 x π x 2.066 = 12.98 rad/s
V(max) = 12.98 x 0.075 =0.973 m/s
V(max) = 97.3 cm/s
Answer:
Explanation:
Let time taken by Jada in driving be t hour .
distance travelled by jada = 55 t
a )
Time of drive by destiny = t - 10 min
= t - .167 hour
distance of travel by destiny = 70 ( t - .167 )
Total distance = 45 miles
55 t + 70 ( t - .167 ) = 45
55t + 70 t - 11.69 = 45
125 t = 56.69
t = .453 hour = 27.21 minutes
b )
distance travelled by Destiny = 70 ( t - .167 )
70 ( .453 - .167 )
= 20.02 miles .
Answer:
Pretty sure its the last answer for model A
Explanation:
Negative a Positive go together and two negatives cant stick
The equation you would have to use for this would be :
Voltage = current * resistance
Voltage = 12 * 4
Voltage = 48
Answer : 48V
