The weight of object with a mass of 8 kg is 78.4 N.
The weight of object with a mass of 0.04 kg is 0.392 N.
The weight of object with a mass of 760 mg is 7.45 N.
<h3>What is weight?</h3>
The weight of an object is the force acting on the object due to gravity.
Weight, W = mg
where;
- m is the mass of the object
- g is acceleration due to gravity, 9.8 m/s²
<h3>Weight of object with a mass of 8 kg</h3>
W = mg
W = 8 kg x 9.8 m/s²
W = 78.4 N
<h3>Weight of object with a mass of 0.04 kg</h3>
W = mg
W = 0.04 kg x 9.8 m/s²
W = 0.392 N
<h3>Weight of object with a mass of 760 mg</h3>
W = mg
W = 0.76 kg x 9.8 m/s²
W = 7.45 N
Thus, the weight of object with a mass of 8 kg is 78.4 N.
The weight of object with a mass of 0.04 kg is 0.392 N.
The weight of object with a mass of 760 mg is 7.45 N.

#SPJ1
Answer:
a:it speed up
b:it should be positive since final
velocity is larger than initial velocity
c:acceleration is approximately 4.5
m/s^2
Explanation:
initial velocity=u=4.47m/s
Final velocity=v=17.9m/s
Time=t=3 seconds
a:the car speed up since the velocity
increased
b:change in velocity is positive
because final velocity is larger than
initial velocity
17.9-4.47=13.43 m/s
c: acceleration=(v-u)/t
acceleration=(17.9-4.47)/3
acceleration=13.43/3
acceleration=4.5 m/s^2
