Answer:
speed
Explanation:
Speed = distance travelled/time taken
Answer:
Cations (positively-charged ions) and anions (negatively-charged ions) are formed when a metal loses electrons, and a nonmetal gains those electrons. The electrostatic attraction between the positives and negatives brings the particles together and creates an ionic compound, such as sodium chloride.
Explanation:
Answer:
a. 156.41m
b. directly over the target
Explanation:
a) At the point of release, the weight will have:
Horizontal:
velocity of 40m/s (same as the plane)
Acceleration of zero since it is not under the influence of any force.
Vertical:
initial Velocity - zero at this instant
Acceleration - Towards the ground with g (9.81m/s^2)
from newton's equation of motion, since its falling under gravity, the horizontal component wont be involved
s = ut + (1/2)at^2
u = initial velocity
a = acceleration
s = displacement
t = time taken
75 = 0 + (1/2)(9.81)t^2
t^2=15.29
t=3.91
t = 3.91s
Applying the time of flight to the horizontal components:
Distance = speed x time
= 40 x 3.91
= 156.41m
B) The pilot looks down at the weight after she drops it. Where is the plane located at the instant the weight hits the ground?
not yet over the target
past the target
directly over the target
not enough information to determine
c. directly over the target. will be the correct answer
Answer:
A single component that can’t be separated
brainliest please ;)
Answer:
132.64m/s
Explanation:
Averagevelocity= distance/time
From the question, the distance d = 825m
time t = 6.22 secs
Using the above formula
We have
average velocity = 825/6.22
= 132.64m/s
