Answer:
Direction is missing
Step-by-step explanation:
Veronica’s velocity was measured as 4.3 m/s. She displaced 20 meters in 4.7 seconds. We know that velocity is a vector quantity. It has both magnitude as well as direction. Velocity is defined as the total distance per unit time I.e.
i.e. the magnitude of velocity is 4.3 m/s
Here, only velocity is given but its direction is missing. So, the missing information is " the direction ".
Answer:
2nd choice
Step-by-step explanation:
Horizontal distance = x
angle = α,
tanα = 15/x, so x = 15/tanα
For A, α = 42°, x = 15/tan42° = 16.66 miles
For B, α = 44°, x = 15/tan44° = 15.53 miles
so the answer is 2nd choice
Answer:
Step-by-step explanation:
Subtract 9.8 from both sides.
<em>The value of x is 4.4</em>.
Answer:
1/16
Step-by-step explanation:
Each coin flip is an independent event so the probabilities are independent
P(T,H,T,H) = P(T) P(H) P(T) P(H)
= 1/2 * 1/2 * 1/2 * 1/2
= 1/16
