that is because they have a strong tendency to donate their valence electron in the last shell to form strong ionic bonds



A wheelbarrow of mass 20 kg accelerates from rest and reaches speed of 10m/S2 in 5 seconds.its force?​

tennis2007.org:

Explanation:

We are asked to find the force of a wheelbarrow. According to Newton"s Second Law of Motion, force is the product of mass and acceleration.

*

1. Calculate Acceleration

The mass of the wheelbarrow is 20 kilograms. We are not given the acceleration, so we must calculate it using the following formula.

*

The wheelbarrow starts at rest or 0 meters per second (initial velocity) and accelerates to reach 10 meters per second (final velocity) in 5 seconds (time).

You are watching: Group 1a elements have similar properties because they

*
10 m/s
*
0 m/s t= 5 s

Substitute these values into the formula.

*

Solve the numerator.

*

Divide.

*

*

2. Calculate Force

Now we know the mass and acceleration of the wheelbarrow

m= 20 kg a= 2 m/s²

Substitute the values into the force formula.

*

*

Convert the units. 1 kilogram meter per square second is equal to 1 Newton, so our tennis2007.org of 40 kilogram meters per square second is equal to 40 Newtons.

An elastic circular bar is fixed at one end and attached to a rubber grommet at the other end. The grommet functions as a torsio

2.1 rad(anticlockwise).

Explanation:

So, we are given the following data or parameters or information in the question above:

=> "The torsional stiffness of the spring support is k = 50 N m/rad. "

=> "If a concentrated torque of mag- nitude Ta = 500 Nm is applied in the center of the bar"

=> "L = 300 mm Assume a shear modu- lus G = 10 kN/mm2 and polar monnent of inertia J = 2000 mln"

Hence;

G × J = 10 kN/mm2 × 2000 mln = 20 Nm^2.

Also, L/2 = 300 mm /2 = 0.15 m (converted to metre).

Where V = k = 50 N m/rad

w = 183.3 θ.

Therefore, w + Vθ = 500 Nm.

= 6.3

Anticlockwise,

θ = 2.1 rad.

Can y’all help me with this plzz, thank you (:

Most likely B.

Because the mass of Cart B is higher than Cart A, its speed must be less than cart A"s speed after the reaction. Therefore, options C and D are not applicable. Because of the ratio of masses between the carts, it would be safe to assume that A is not the tennis2007.org. Although, I would still give option A a 7 0

Light is energy that travels in waves and is produced by hot, energetic objects, while sound and heat energy are created with vibration and radiation, convection, or conduction.

Explanation:

Light bulbs are hot, energetic objects. You know the light bulb needs energy because you have to turn the light switch on to provide electricity for it. The electricity flows through either a thin metal wire or a gas. The wire or gas glows and gives off light when heated.
