Answer:

1 m/s²

Explanation:

The following data data were obtained from the question:

Net force (F) = 10 N

Initial mass (m1) = 5 Kg

Initial acceleration (a1) = 2 m/s²

Final mass (m2) = double the initial mass = 2 × 5 = 10 kg

Final acceleration (a2) =?

The final acceleration of the object can be obtained as follow:

Recall:

Force (F) = mass (m) × acceleration (a)

F = m × a

Keeping the force constant, we have

m1a1 = m2a2

With the above formula, we can obtain the final acceleration of the car as follow:

Initial mass (m1) = 5 Kg

Initial acceleration (a1) = 2 m/s²

Final mass (m2) = 10 kg

Final acceleration (a2) =?

m1a1 = m2a2

5 × 2 = 10 × a2

10 = 10 × a2

Divide both side by 10

a2 = 10 /10

a2 = 1 m/s²

Therefore, the final acceleration of the car will be 1 m/s²

The force between two charged bodies is called ______________.

stepladder [879]

The Coulomb force between two or more charged bodies is the force between them due to Coulomb's law. If the particles are both positively or negatively charged, the force is repulsive; if they are of opposite charge, it is attractive. ... Like the gravitational force, the Coulomb force is an inverse square law.

Two identical 9.10-g metal spheres (small enough to be treated as particles) are hung from separate 300-mm strings attached to t

Musya8 [376]

Answer:

$n = 1.266\times 10^{12}$

Explanation:

Given data:

mass of sphere is 10 g

Angle between string and vertical axis is $\theta = 13 degree$

thickness of string 300 mm = 0.3 m

$sin\theta =\frac{2}{0.3 m}$

r =0.3 sin 13 = 0.067 m

$Fe = \frac{ kq_1 q-2}{d^2}$

$Fe = \frac{kq^2}{(2r)^2} = mg tan\theta$

$q^2 = mg tan\theta \frac{(2r)^2}{k}$

$= 0.0091 \times 9.8 tan13 \times \frac{(2\times 0.067)^2}{9\times 10^9}$

$q^2 = 4.10\times 10^{-14}$

$q = 2.026 \times 10^{-7} C$

q = ne

$n = \frac{1.6\times 10^{-19}}{2.02\times 10^{-7}}$

$n = 1.266\times 10^{12}$

a particle moves at a constant speed in a circular path. the instantaneous velocity and instantaneous acceleration vectors are:

Lilit [14]

The instantaneous velocity always tangential to circular path and instantaneous acceleration always points towards the center of circle.

What is instantaneous?

The definition of instantaneous velocity is the rate of change of location during a time that is virtually zero .The replica was. The definition of instantaneous velocity is the speed of a moving item at a certain instant in time.

The rate of change of location during a relatively brief period of time is known as instantaneous velocity.

In the limit when the time (and thus the displacement) between the two places approaches zero, the instantaneous acceleration is the average acceleration between two points on the route.

so, both of them are perpendicular to each other.

To learn about instantaneous velocity

The ability to clearly see objects at a distance but not close up is properly called ________. The ability to clearly see object

melamori03 [73]

Answer:

Hyperopia

Explanation:

In hyperopia ,people face difficulties to see close up object , but can see object easily which are at a distance.

The main reason of hyperopia is our eyeball.When our eyeball become too short , then light focus behind the retina. Sowe will face problem to see near object but we can see distance object easily. Hyperopia is the opposite of nearsightedness. Hyperopia can be corrected by using contact lenses.
