Answer:
The acceleration is 10 m/s²
Explanation:
The question seeks to show the relationship between force, mass and acceleration. Hence, the formula to be used here is that of force which is shown below
F = ma
where F is the force (800 N)
m is the mass (80 kg)
a is the acceleration (unknown)
From the formula above (Force = mass multiplied by acceleration)
800 N = 80 kg × a
a = 800 ÷ 80
a = 10 m/s²
The correct options are:
<span>B. Radiation is heat flowing in waves.
C. Conduction is heat flowing between two objects that are touching each other.
In fact, radiation is heat transferred by electromagnetic waves, while conduction is the heat transfer between touching objects (the particles of one object collide with the particle of the other object, and so heat is transferred via the transfer of kinetic energy between the molecules).
Instead, option A is wrong (because conduction </span>is the heat transfer between touching objects) and option D is wrong because convection is the heat flowing when a liquid or a gas carries the heat.
Explanation
If you graph the force on an object as a function of the position of that object, then the area under the curve will equal the work done on that object, so we need to find the area under the function to find the work
Step 1
find the area under the function.
so
Area:
so
therefore, the answer is

Answer:
i assume the system is in equilibrium
Explanation:
(W_p-T)(2)+W_b(2.5)= T(sin 45 degrees)(5)
T(((sin 45 degrees)(5)) + 2) = (W_p)(2) + W_b(2.5)= T(5.5355)
