At which position is the LOWEST potential energy?

Answer:

Advantages

If there is a fault in one of the electric appliances, the current is able to pass through different paths of the circuit.

Disadvantages

In parallel circuits, we cannot increase the voltage since the resistance decreases in the parallel circuit.

Answer:

3kg sledgehammer swung at 1.5 m/s

Explanation:

Small Sledgehammer:

Mass:3.0

Velocity:1.5

MASS×VELOCITY=MOMENTUM

3.0×1.5= 4.5 (momentum)

Large Sledgehammer:

Mass:4.0

Velocity:0.9

4.0×0.9=3.6 (momentum)

higher momentum is the smaller Sledgehammer.

Answer:

A. New mountains are created

Answer:

Explanation:

When the object falling attains terminal velocity , net force on it becomes zero. That means drag force becomes equal and opposite to its weight.

So drag force = mg

where m is mass of falling body and g is acceleration due to gravity .

The drag force is constant . It is doing work against the weight of falling body . Object is falling v m /s . That means drag force is doing work per second as follows

Work done per second = force x displacement per second

= mg x v

So

Power of drag force = mgv.

Pd = mgv.

Answer:

0.833 Hz

Explanation:

While, there are plenty of ways to calculate frequency, the one formula you should use in this case is:

#times/seconds --> 85/102

= 0.833 Hz

Answer: 3.0 m/s

Explanation:

Answer In the field of physics, tension is called the force that is exerted by the action of a cable, rope, chain or other similar solid object. ... Since tension is a magnitude of force, it is measured in newtons and is always measured in a direction parallel to the chord on which it is applied.

Explanation:

Answer:

10.2 km

Explanation:

Displacement is the shortest distance from your original position after movement.

Now, the Zambeef delivery truck moves 18 km north and then 10 km east and then 16 km south.

This means that vertically the truck is 2km short of the 18 km he travelled north..

So we can find the displacement using pythagoras theorem..

Let d be the distance from the current position to the initial position.

Thus;

d² = 2² + 10²

d² = 4 + 100

d = √104

d ≈ 10.2 km

I have attached a diagram showing the direction of this displacement

Complete question is;

Describe how α-radiation is similar to β-radiation?

Answer:

Explained below

Explanation:

The similarity between both alpha radiation and beta radiation is that in both cases, they both show deflection when they go through electric and magnetic fields. Although alpha deflects towards the negative plate while bets deflects towards the positive plate.

Secondly they both have high speeds. Just that alpha is from the helium nucleus while beta is from electrons.

Answer:

True.

Explanation:

Newton's Second Law of Motion states that the acceleration of a physical object is directly proportional to the net force acting on the physical object and inversely proportional to its mass.

Mathematically, it is given by the formula;

Force = mass * acceleration

[tex] F = ma[/tex]

Centripetal acceleration is given by the formula;

[tex] Acceleration, a = \frac {v^{2}}{r}[/tex]

Where;

v is the velocity.

r is the radius.

The equation for centripetal force can be derived by substituting the equation for centripetal acceleration into Newton’s second law.

Let centripetal force be Fc

Fc = ma

Substituting the value of "a" into the above formula;

[tex] Fc = m \frac {v^{2}}{r} [/tex]

[tex] Fc = \frac {mv^{2}}{r} [/tex]

From the postulation of the parallelogram law of vectors, the resultant vector is 94 m.

The resultant vector refers to that vector that can have the same effect as the two vectors acting together. In this case, we have to use the parallelogram law of vectors.

Thus;

R= √(101)^2 + (85)^2 - 2(101 * 85)cos 60

R = √17426 - 8585

R = 94 m

He throws a snowball with a force of 4 N to the right, while the snowball pushes the person with a force of 4 N to the left. The given scenario is balanced because the same amount of force is acting in both direction.

Answer:

a. The desk seat will push back on the bottom (reaction force).

b. baseball hit the bat (reaction force)

c. The phone screen presses on your finger (reaction force).

Explanation:

The third law of Isaac Newton explains that, to every force, there is an equal and opposite force. The initial force is called the ACTION FORCE while the opposite force is called the REACTION FORCE. The reaction force for the following action forces in this question are:

- Your bottom pushing on your desk seat (action force)- The desk seat will push back on the bottom (reaction force).

- A bat hitting a baseball (action force) - baseball hit the bat (reaction force)

- Your finger pressing on your phone screen while texting (action force) - The phone screen presses on your finger (reaction force).
