Mass of the fertilizer bag is 165.82 kg

According to Newton's law,

F = m*a

So, m= F/a

m= 131/0.790

m= 165.82 kg

Mass is the measure of matter of a body.

Newton has stated three laws of motion. The first law states that every object will remain at rest or in uniform motion in a straight line unless an external force compels it to change its state of action .

The second law states that the acceleration of an object is dependent upon two variables - the net force acting upon the object and the mass of the object.

The third law states that every action has an equal and opposite reaction.

The collision, Miguel is moving in the opposite direction at 1.2 m/s.

Define collision.

A collision in physics is any situation in which two or more bodies quickly exert forces on one another. Despite the fact that the most common usage of the word "collision" refers to situations in which two or more objects clash violently, the scientific usage of the word makes no such assumptions.

Miguel's post-collision velocity can be determined using the law of conservation of momentum.
Momentum is a vector quantity and is equal to mass times velocity (p=mv). Before the collision, the momentum of the system (Miguel + Fernando's car) is equal to (m1=72kg)(v1=4m/s) + (m2=125kg)(v2=0m/s) = 782 kg*m/s.
After the collision, the momentum of the system is equal to (m1=72kg)(v1=?m/s) + (m2=125kg)(v2=2m/s) = 782 kg*m/s.
By solving for v1 we can find that Miguel's post-collision velocity is -1.2 m/s.
This means that after the collision, Miguel is moving in the opposite direction at 1.2 m/s.

The acceleration of the racquetball  from 5 m/s to 31.0 m/s in a time interval of  0.0150 seconds is 1733.3m/s².

Acceleration of an object is the rate of change in its velocity. It is a vector quantity having both direction and magnitude.  It is the ratio of change in velocity to the time interval. Velocity is the rate of speed of an object.

A change in magnitude or direction or change in both for velocity will accelerate the object.

a = Δv/t.

Given that, v1 = 5 m/s

v2 = 31 m/s

then Δv =31 m/s -5 m/s = 26 m/s

Time interval = 0.0150 s

Acceleration = 26 m/s /0.0150 s = 1733.3 m/s²

Therefore, the acceleration of the fighter pilot does not exceed the limit of 75 m/s². Hence, it will not black out.

Answer:

\(V_{B/A}=2i+2k\)

Explanation:

The relative velocity can be calculated by means of the difference between vector B minus vector A.

\(V_{A}=i+2j-3k\\V_{B}=3i+2j-k\\V_{B}-V_{A}=(3-1)i + (2-2)j+(-1-(-3))k\\V_{B/A}=2i+2k\)

To estimate the Coulomb charging energy for a metallic sphere embedded in silicon, we can use the formula for the electrostatic energy of a charged capacitor. The charging energy, also known as the electrostatic energy or the electrostatic potential energy, is given by:
E = (1/2) * Q^2 / C
Where:
E is the charging energy,
Q is the charge on the metallic sphere, and
C is the capacitance of the system.

For a metallic sphere embedded in silicon, the capacitance can be approximated by the parallel plate capacitor formula:
C = ε0 * A / d
Where:
C is the capacitance,
ε0 is the vacuum permittivity (8.854 x 10^-12 F/m),
A is the surface area of the metallic sphere (4πr^2, where r is the radius), and d is the distance between the metallic sphere and the surrounding medium (in this case, silicon).
To estimate the charging energy, we need to know the charge on the metallic sphere. Without that information, we cannot provide a specific value for the Coulomb charging energy. The charging energy depends on the magnitude of the charge, which can vary depending on the system and the charging process.
If you have the charge value for the metallic sphere, please provide it so that we can calculate the charging energy.

The terminals of a\(12\) v battery are connected by a \(1.0-mm\) diameter copper wire. The wire needs to be \(7.2\) km in length in order to have a current of 10 A.

Copper wire is a type of electrical wiring used in the construction of buildings and other structures. It is made of highly conductive copper, a material that is strong and durable enough to withstand the rigors of everyday use. Copper wires are typically covered with a protective sheath of insulation to protect them from electric shock, corrosion, and other environmental hazards. Copper wires are used in a variety of applications, including telecommunications, power generation, distribution, and control systems.

The length of the wire can be determined using Ohm's Law. This states that the current through a wire is equal to the voltage across the wire divided by the resistance of the wire. Therefore, the length of the wire needed to achieve a current of 10 A is:

Length =\((12 V)/(10 A x 1.0 mm2/m x 1.68 x 10-8 Ω /m)\) = \(7.2\) km.

The leads that measure the potential difference between two electrodes are called "leads of electrocardiogram or ECG" or "electrodes leads."

The leads that measure the potential difference between two electrodes are called "leads of electrocardiogram or ECG" or "electrodes leads." The ECG machine is used to record and monitor the electrical activity of the heart using electrodes that are connected to the skin. The electrical activity is measured by leads that measure the potential difference between two electrodes. Each ECG electrode has a positive and negative charge. The electrodes are attached to the patient's skin on their chest, arms, and legs. The leads then measure the electrical activity of the heart and record it as a graph on a screen or paper.

Electrodes are used to monitor the electrical activity of the heart by detecting the changes in electrical signals that are produced as the heart muscle contracts and relaxes. These electrodes leads are capable of picking up the electrical signals and transmitting them to a machine that records and interprets the signals. The machine records the signals on a paper or a screen and can be used to diagnose a range of heart conditions. ECGs are commonly used in hospitals and clinics, and they are usually performed by a cardiologist or a specially trained technician.

The initial speed of the projectile is 18.5m/s

Projectile motion is the motion of an object thrown into the air under gravity. Examples of projectiles include a fired bullet, a thrown javelin e t.c

When a projectile is launched horizontal, it's horizontal range is given as R = u(√2h/g)

R = 300ft = 91.44meters

h= 120m

therefore 91.44= u( √ 2×120/9.8)

91.44 = u ( √24.49)

91.44 = 4.95 u

divide both sides by 4.95

u = 91.44/4.95

u = 18.5m/s

Answer:

When viewed from above, the current in the coil should point towards the top-right corner of the picture.

Explanation:

The current in this coil have only two possible directions: clockwise or counter-clockwise. However, since the diagram shows the coil from above, not from a cross-section, just saying clockwise or counter-clockwise might be ambiguous. The statement that the current is directed towards the top-right corner of the picture is equivalent to saying that when viewed from the lower-right corner of this diagram, the current in the coil is moving clockwise.

Note that at the center of this picture, the current is parallel to the magnetic field- there will be no force on the coil at that position. On the other hand, (also when viewed from above,) at the top-right corner and the lower-left corner of the coil, the current in the coil will be perpendicular to the magnetic field. That's where the force on the coil will be the strongest.

With that in mind, apply the right-hand rule to find the direction of the force on the coil in each of the two possibilities.

Assume that when viewed from above, the current is flowing towards the top-right corner of the picture. Consider the wire near the top-right corner of this coil (as viewed above on this picture.) The current will be going into the picture into the magnetic field. By the right-hand rule, the current on the wire near that point should be pointing towards the bottom of this picture. (Point fingers on the right hand in the direction of the current \(I\). Rotate the right hand such that when curling the fingers, they point in the direction of the magnetic field \(B\). The direction of the right thumb should now point in the direction of the force on the wire \(F\).)

Based on the same assumption, the current in the wires near the bottom left corner of this coil will be pointing out of the picture. By the right hand rule, the magnetic force on the coil in that region should be pointing towards the top of this picture. Combing these two forces, the coil would indeed be rotating around the center of this picture in the direction shown in the diagram.

It can also be shown that if the current points towards the bottom left corner of the picture when viewed from above, the coil will be rotating about the center of this picture in the opposite direction.
