A 2600 kg car traveling to the north is slowed

Physics
1 answer:
Nadusha1986 [10]3 years ago
4 0

Answer:

19.2 m/s

Explanation:

Let's say north is the positive direction.

Impulse = change in momentum

F Δt = m Δv

(-6750 N) (1.73 s) = (2600 kg) (v − 23.7 m/s)

-11677.5 Ns = (2600 kg) (v − 23.7 m/s)

-4.49 m/s = v − 23.7 m/s

v = 19.2 m/s

Eating. Your muscles in your arms and mouth use energy to feed itself. Then your body digest the food which also takes energy.

Sleep. When your tired, you don’t have much energy. It is said that you use more energy while your sleeping. But how do you become energized if you were using even more energy than before?

A right triangle with the base labeled 40 meters and the height labeled 30 meters. The hypotenuse is a dotted arrow labeled R. W
Pepsi [2]

Answer:

The magnitude of the resultant vector R is 50 meters ⇒ 2nd answer

Explanation:

<u><em>The resultant vector</em></u> is the vector sum of two or more vectors

If the two vectors perpendicular to each other, then the magnitude of

the resultant vector is the square root of the sum of their squares

If x and y are two vectors perpendicular to each other, then the

magnitude of its resultant vector R is:

→ R=\sqrt{x^{2}+y^{2}}

Lets solve the problem

A right triangle with the base labeled 40 meters and the height labeled

30 meters

The hypotenuse is a dotted arrow labeled R

→ The base and the height of the right triangle are perpendicular

→ The hypotenuse is the resultant vector of them

Assume that x represents the base of the triangle and y represents the

height of it

By using the rule above

→ x = 40 m , y = 30 m

→ R=\sqrt{x^{2}+y^{2}}

→ R=\sqrt{(40)^{2}+(30)^{2}}

→ R=\sqrt{1600+900}

→ R=\sqrt{2500}=50

<em>The magnitude of the resultant vector R is 50 meters</em>

Determine the electrical force of attraction between two balloons with separate charges of +3.5 × 10-8 C and -2.9 × 10-8 C when
kenny6666 [7]

Answer:

The electrical force of attraction between the balloons is 2.16\times 10^{-5}\ N.

Explanation:

Given that,

Charge 1, q_1=+3.5\times 10^{-8}\ C

Charge 2, q_2=-2.9\times 10^{-8}\ C

Distance between the charges, d = 0.65 m

We need to find the electrical force of attraction between two balloons. It is given by the formula as :

F=k\dfrac{q_1q_2}{d^2}\\\\F=9\times 10^9\times \dfrac{3.5\times 10^{-8}\times 2.9\times 10^{-8}}{(0.65)^2}\\\\F=2.16\times 10^{-5}\ N

So, the electrical force of attraction between the balloons is 2.16\times 10^{-5}\ N. Hence, this is the required solution.
