Physics
1 answer:
Reil [10]3 years ago
3 0

Answer:

Yes

Explanation:

When an object has more mass it takes more gravity to keep it down therefore producing friction which in return reduces the amount of kinetic energy created. A change in an object's speed has an greater effect on its kinetic energy. than a change in its mass has, because kinetic energy is proportional to.

A brick of mass 1.15 kg is attached to a thin (massless) cable and whirled around in a circle in a vertical plane. The circle ha
stira [4]

Explanation:

It is given that,

Mass of the brick, m = 1.15 kg

Radius of the circle, r = 1.44 m

The cable will break if the tension exceeds 43.0 N

Let v is the maximum sped can have at the bottom of the circle before the cable will break. At the bottom of the circle, the net force is equal to the centripetal force along with the weight of the brick. So,

T=\dfrac{mv^2}{r}+mg

\dfrac{T}{m}-g=\dfrac{v^2}{r}

v=\sqrt{(\dfrac{T}{m}-g)r}

v=\sqrt{(\dfrac{43}{1.15}-9.8)\times 1.44}

v = 6.30 m/s

So, the maximum speed of the brick at the bottom of the circle before the cable will break is 6.3 m/s. Hence, this is the required solution.

Having more than one atom in its molecule doesn't make
a substance a compound.  It's only a compound if it has
atoms of different elements in its molecule.

Both atoms in an Oxygen molecule are the same element ... Oxygen.

Find the acceleration produced.
krok68 [10]

Answer:

0.67m/s²

Explanation:

Given parameters:

Mass of toy  = 1.2kg

Force applied = 0.8N

Unknown:

Acceleration   = ?

Solution:

According to newton's second law of motion;

      Force  = mass x acceleration

Now,

      Acceleration = \frac{Force}{mass}

     Acceleration  = \frac{0.8}{1.2}   = 0.67m/s²
