Answer:
Distance is greater than the displacement.
Step-by-step explanation:
We are given that a train on a straight track goes in the positive direction.
We have to find that distance covered by the train is greater than, lees than or equal to its displacement.
Train covered distance in positive direction=6.7 km
Train covered distance in back=4.0 km
Distance covered by the train=6.7+4=10.7 Km
Because distance is the length of path covered by object.
Displacement =Final position -Initial position
Displacement =6.7-4=2.7 km
10.7 > 2.7
Distance > Displacement
Hence, Distance is greater than the displacement.
Answer:
Step-by-step explanation:
what 3x9
To answer, first, convert the given velocity in km/h to m/s as shown below,
(144 km / hr) x (1000 m / 1 km) x (1 hr / 3600 s) = 40 m/s
The acceleration (a) is solved by through the equation,
a = (Vf - Vi) / Δt
where Vf and Vi are final and initial velocities, respectively and Δt is change in time. Substituting the known values,
a = (0 - 40 m/s) / 12 s = -3.3 m/s²
Thus, the answer to this item is letter B.
There are 2100 cups in the package.
Step-by-step explanation:
Given,
Number of green cups in package = 630
This represent 30% of the total package.
Let,
x represent the total number of cups in package.
30% of x = 630
Dividing both sides by 0.30
There are 2100 cups in the package.
