Answer:
i dont think anything will happen so maybe A: the wall is larger than you.
Explanation:
Q.1
Answer . Momentum = mass x velocity
Momentum/mass = velocity
5/0.8 = velocity
6.25 m/s = velocity
Q.2
Answer . F = ma => a = f/m => a = 7/3.2 => a = 2.1875m/s²
Each of the choices may be considered right depending on the use
of context or on how terms are defined, but the one that is most correct is:
"Controlled experiments
produce valid data"
Controlled experiments are experiments in which factors which are
not the interest of the study or which are not being studied are controlled or
accounted for in the design, so that resulting data are less likely to be
caused by some anomaly or by some variable other
than those being
studied. In usual research scenarios it is not the data itself that
is acted upon in the <span>experiment - it is the experiment itself, the
factors and the physical processes that will eventually yield data.</span>
Answer:
The final position is 36 feet.
Explanation:
initial position, d = 330 feet
speed, v = 3 feet per minute
time, t = 30 minute
now the time is 32 minute
time interval = 2 minute
So, the distance in 2 minutes is
d' = 2 x 3 = 6 feet
So, the final position is
D = 30 + 6 = 36 feet
Answer:
The normal force will be lower than the gravitational force acting on the car. Therefore the answer is N < mg, which is <em>option B</em>.
Explanation:
Over a round hill, the centripetal force acting toward the the radius of the hill supports the gravitational force (mg) of the car. This notion can be expressed mathematically as follows:
At the top of a round hill
At the foot of a round hill
