Under the effect of the planet's acceleration from gravity, a stone put on Venus will fall 35.48 m in 2 seconds.

The following formula can be used to determine the distance that an object falls while being pulled by gravity:

d = 1/2 * g * t^2

where g is the gravitational acceleration, t is the passing of time, and d is the distance fallen. On Venus, the acceleration brought on by gravity is equivalent to 8.87 m/s2.

The distance fell at t = 2 seconds would be as follows:

d = 1/2 * 8.87 m/s * (2 s), which is 1/2 * 8.87 m/s * (4 s), or 8.87 * 4 = 35.48 m.

The stone will therefore travel 35.48 metres on Venus in 2 seconds.Acceleration is the rate at which an object's velocity changes over time. It has metres per second squared (m/s2) as its SI unit of measurement and is a vector quantity.

Angle between two vectors:

Two vectors can be used to determine the angle between them by using the dot product formula. The dot product is the product of the magnitudes of the two vectors and the cosine of the angle between them. If we have two vectors, ⃗ and −⃗, the dot product of these two vectors can be determined as follows:

⃗ ⋅ −⃗ = |⃗||−⃗| cos θ

where θ is the angle between the two vectors.

To find the angle between two vectors, we can use the arccosine function, which is the inverse of the cosine function. The arccosine function returns the angle, in radians, whose cosine is a given value. Hence, to find the angle between two vectors, we can use the following formula:

θ = arccos (⃗ ⋅ −⃗ / |⃗||−⃗|)

Note that the dot product can only give us the cosine of the angle between two vectors, so we have to use the arccosine function to find the actual angle. The result will be in radians, but it can easily be converted to degrees if necessary.

In summary, to find the angle between two vectors, we first find the dot product of the two vectors, then divide that result by the product of the magnitudes of the two vectors. Finally, we find the arccosine of that result to obtain the angle between the two vectors.

Both bodies must be charged in order to repel each other, but they do not both have to be charged to attract each other.

The attractive force between two bodies is due to the electromagnetic force, which acts between charged particles. So, if one of the bodies is charged, it will experience an attractive force toward a neutral body. However, if both bodies are charged with the same type of charge (i.e., both positive or both negative), they will experience a repulsive force.

If two bodies repel each other, it means that they are both charged with the same type of charge (i.e., both positive or both negative). This is because like charges repel each other and opposite charges attract. So, in order for two bodies to repel each other, they must both be charged.

The velocity is 0.1 m/s, west. This is an inelastic collision.

The velocity of the 0.2 kg ball after the collision is 0.1 m/s, west. This is an inelastic collision, meaning that some energy is lost in the form of heat, sound or other forms of internal energy. You can determine this because the velocities of both balls have changed, and the final kinetic energy is different from the initial kinetic energy. A collision is an event in which two or more objects come into contact and interact with each other for a short period of time. During a collision, the objects exchange momentum and energy, causing changes in their velocity, direction, or other physical properties. Collisions can be classified into two types: elastic and inelastic. In an elastic collision, the total kinetic energy of the system is conserved, while in an inelastic collision, some of the kinetic energy is converted into other forms of energy such as heat or sound. The type of collision is determined by the relative magnitudes of the initial and final kinetic energies of the system.

The resistance that would produce a current of 400 amperes from a socket putting out 2,000 volts is 5 ohms, calculated using the formula R = V/I, where V = 2,000 volts and I = 400 amperes.

Explanation:

So, a resistance of 5 ohm would result in a current of 400 amps from a 2,000 volt plug.

The opposition that a substance provides to the flow of electric current is referred to as resistance. The capital letter R represents it. The ohm is the standard unit of resistance, which is often written as a word and occasionally represented by the capital Greek letter omega. Resistance is a measure of an electrical circuit's resistance to current flow. Resistance is measured in ohms, which is represented by the Greek letter omega (ohm). A conductor's resistance is defined as the ratio of potential difference across its end to current flowing through it. It is measured in ohms (omega).

3.6 kmph speed (in km h –1) you could theoretically accelerate a car (mass: 1t) with this energy.

The speed to which you could theoretically accelerate a car of mass 1 metric ton (1000 kg) depends on the amount of energy available to do so. In physics, the relationship between energy and velocity is given by the formula:

Where m is the mass of the car and v is its velocity. So to find the velocity, we can rearrange the formula to solve for v:

If we assume that the energy available for acceleration is E, then the velocity can be calculated as follows:

Note that the units of energy must be consistent with those in the accelerate formula. In this case, if E is given in joules, then the velocity will be in meters per second. To convert the velocity to km/h, we need to multiply by (3600 s/hr)/(1000 m/km) = 3.6. So:
