D. all of these
all of these use electricity
Hope I helped!
Tension in the rope due to applied force will be given as

angle of applied force with horizontal is 37 degree
displacement along the floor = 6.1 m
so here we can use the formula of work done

now we can plug in all values above


So here work done to pull is given by 691.8 J
The volume decreases, by a factor of
(the original pressure/(125 kPa).
Answer:
BOTH the size of the force AND the mass of the object
Explanation:
Acceleration of an object is the rate of change of its velocity.
The relation between force, mass and acceleration is given by the formula as follows :
F = ma
m is mass
a is acceleration
It would mean that the change in motion or the acceleration of an object depends on both the size of the force and the mass of the object. Hence, the correct option is (c).
Answer:
13 530 482
Explanation:
H2 + I2 ------> 2HI
start (mol) 0.3785 0.3818 0
change (mol) -0.3534 -0.3534 +0.7067
equilibrium (mol) 0.0251 0.0284 0.7067
concentra (mol/L) 0.0068 0.0077 0.1926
