Answer:
The acceleration in the system and in the rope is same as 5.88 m/s2.
Step-by-step explanation:
The figure shows two blocks of m1 = 0.8 Kg and m2 = 0.2 kg if the block of mass m2 is dragged by the block of mass m1 calculate the acceleration of the system and the acceleration of the rope
Let the acceleration is a and the tension in the string is T.
Use Newton's second law
Answer:
C.
Step-by-step explanation:
ACE is a straight line that connects to line AB and line DE.
AB & ED have same gradient which mean that it is parallel.
A vertical parabola is: y = a(x-h)² + k
where (h,k) is the vertex and "a" is the vertical stretch/shrink.
A negative sign in front of the "a" represents a reflection over the x-axis.
y = a(x-0)² + 0
y = a(x)²
Answer: B (y = 3x²)
Answer:
We failed to accept null hypothesis
Step-by-step explanation:
x= 5.74
Standard deviation =
n = 65
We will use z test
Formula :
Substitute the values :
Refer the z table for p value
p value = 0.0314
α = 0.10
p value < α
So, we failed to accept null hypothesis
