Answer:

At the maximum height

Explanation:

The gravitational potential energy of an object is the energy possessed by the object due to its position in the gravitational field.

Mathematically, it is given by:

PE=mgh

where

m is the mass of the object

g is the acceleration due to gravity

h is the height of the object relative to the ground

From the formula, we see that the potential energy is directly proportional to the height of the object above the ground: therefore, the larger the value of h, the larger the potential energy of the object.

Therefore, the object has the maximum potential energy when it is at the highest position above the ground.

Which of the following capacitor can store more data in DRAM?
Neko [114]

Answer:

Stacked - Cell

Explanation:

DRAM is an acronym that means Dynamic Random access memory. It is a type of random access semiconductor memory that stores it's data in a memory cell where a tiny capacitor and a transistor are.

A Trench Capacitor, or otherwise called Deep Trench Capacitor(DTC). They can store only between 4 mb and 256 mb

Stacked Cells occur when individual batteries are stacked together, to achieve a higher voltage and or Power. They can store up to 1 GB of data.

Planar Capacitor, unlike stacked cells and trench capacitors, can only store data of not more than 1 mb. Planar Capacitor happens to be the smallest out of the three.

From the above explanation, it is obvious that Stacked Cells is the answer.

Calculate the kinetic energy in joules of a 1500 kg automobile moving at 17 m/s . express your answer to two significant figures
Sidana [21]
Kinetic energy = 1/2 (mass)*(velocity)^2

ke = 1/2 (1500kg) (17m/s)^2
ke = 216750 kg*m^2/s^2 = 216750 Joules

(sorry, I don't know significant figures. but this is otherwise the correct answer with the right units. hope this helps!! :))

A proton travels at a velocity of 3.0x10^6 m/s in a direction perpendicular to a uniform magnetic field.
Virty [35]

Answer:

0.239 T

Explanation:

Applying,

F = Bvqsin∅................ Equation 1

Where F = magnetic force, B = magnetic Field, q = charge of a proton, v = velocity of proton, ∅ = angle between the velocity and the magnetic field.

make B the subject of the equation

B = F/(vqsin∅)................. Equation 2

From the question,

Given: F = 1.15×10⁻¹³ N, v = 3.0×10⁶ m/s, ∅ = 90°(perpendicular)

Constant: q = 1.602 x 10⁻¹⁹ C

Substitute into equation 2

B =  1.15×10⁻¹³ /(3.0×10⁶×1.602 x 10⁻¹⁹×sin90°)

B = 1.15×10⁻¹³/(4.806×10⁻¹³)

B = 0.239 T.

Hence the magnetic field = 0.239 T

Suppose you are running late in the morning and drying your hair in the kitchen with the hairdryer plugged into the outlet with
lesantik [10]

Answer:

Explanation:

It is given that Hair dryer , Toaster and coffeepot are working simultaneously with power 1200 W , 700 W and 800 W respectively.

So the total power of system is P_t=1200+700+800=2700\ W

it is given that they work properly until toast is on.

By switching on the toast, appliance stop working because it may cause the circuit to break to safeguard the circuit.

Circuit breaker frame  are used in home to prevent the short circuit

The energy of an onject as it is in motion is defined as?
Ivan

The energy of an object as it is in motion is defined as Kinetic energy.

<u>Explanation:</u>

The energy that is attained by an object when it is moving is called as Kinetic energy. It is the amount of energy that is essential for inducing an acceleration in an object and making it to displace from its idle position to the destination. When an object attains the acceleration it can have this kinetic energy until there is a change in the speed of the object with which it moves.

The forms of energy changes and it can take any form like thermal, electrical, electromagnetic,etc. Potential and kinetic energy are the two things under which these forms are energy are grouped. There can be a transferring of Kinetic energy from one object to another. The kinetic energy can also take any form of energy.
