Answer:
horse power of the truck 39,000 kgm²s⁻³
Explanation:
Calculate horse power of the truck.
Work = force x distance
where, force = mg = 2000 kg x 9.8 m/s² = 19,600 kgm/s²
distance = 10 meter
Work = 19,600 kgm/s² x 10 meter
= 196,000 kgm²s⁻²
Power = work / time
= 196,000 kgm²s⁻² / 5 seconds
= 39,000 kgm²s⁻³

In scientific contexts, mass is the amount of "matter" in an object (though "matter" may be difficult to define), whereas weight is the force exerted on an object by gravity.
Answer:
E = 1.04*10⁻¹ N/C
Explanation:
Assuming no other forces acting on the proton than the electric field, as this is uniform, we can calculate the acceleration of the proton, with the following kinematic equation:
As the proton is coming at rest after travelling 0.200 m to the right, vf = 0, and x = 0.200 m.
Replacing this values in the equation above, we can solve for a, as follows:
According to Newton´s 2nd Law, and applying the definition of an electric field, we can say the following:
F = mp*a = q*E
For a proton, we have the following values:
mp = 1.67*10⁻²⁷ kg
q = e = 1.6*10⁻¹⁹ C
So, we can solve for E (in magnitude) , as follows:
⇒ E = 1.04*10⁻¹ N/C
Explanation:
USANDO LA SEGUNDA LEY DE NEWTON:
<em>m</em> = 10.0 N/ = 10.0 kg
it’s c because a compound is two or more elements chemically reacting
