Answer:
In selecting either a box or open end wrench, care should be taken to see that the wrench properly fits the nut.
Explanation:
Answer:
The car exerts the same sized force on the bug as the bug exerts on the car.
Explanation:
Given that
Speed of car = 70 mph
Third law of Newton's
It state that when an object A apply force on the another object B then object B also apply the same force on the object A but in opposite direction .This is known as action reaction .In simple words every action and reaction.
By using the third law of concept,when car and a bug collides then car exerts the same sized force on the bug as the bug exerts on the car.
Answer:
The combination of elements most likely to comprise the circuit are resistor, inductor and capacitor
Explanation:
The impedance of an LCR circuit shown as
Z = √R² + (X↓l - X↓c)²
Z = √R² + (2π∨L - 1/2π∨c)²
Variation of Z with respect to υ is shown in the figure.
As υ increases, Z decreases and so the current increases.
At υ = υ↓r
Z is minimum, current is maximum. Beyond
υ = υ↓r
Z increases and so current decreases.
so the combination of circuit elements that is most suitable to comprise
the circuit is R, L and C.

Answer:
Norma’s average speed is 41.9 km/h.
Explanation:
The average speed is given by:
Where:
: is the total distance
: is the total time
We can find the total distance as follows:
Now, the total time is:
Hence, the average speed is:
Therefore, Norma’s average speed is 41.9 km/h.
I hope it helps you!
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>
