Answer is: <span>the mass of the body is 35 kg.
</span>Newton's second law of motion: F = m · a.
F - <span> force applied.
m - </span><span>mass of the object receiving the force.
</span>a<span> - the acceleration of the object.
</span>F = 350 N.
a = 10 m/s².
m = ?
m = F ÷ a.
m = 350 N ÷ 10 m/s².
m = 35 kg.
<span>One newton is the force needed to accelerate one kilogram of mass at the rate of one metre per second squared in direction of the applied force.</span>
Answer:
The correct option is (d).
Explanation:
- The energy a particle has because of its charge and its position relative to another particle is called thermal energy.
- It is the energy that comes from heat. This is generated by the movement of the particles in an object.
- Thermal energy is the energy an object or system has due to the movement of particles within.
Hence, the correct option is (d).
Answer:
One way to increase acceleration is by changing the velocity.
Answer:
.team 1 a = 20.8 m/s² team 2 a = 19.2 m/s²
Explanation:
Let's use Newton's second law to calculate the acceleration of the two groups
F = ma
a = F / M
Group 1
a = 9 1354/9 65
a = 20.8 m / s²
Group 2
a = 9 1364/9 71
a = 19.2 m / s²
If the two groups pull against each other, group 1 should win, by creating a greater acceleration.
Δa = 20.8 -19.2
Δa = 1.6 m / s²
