4200 Newtons

Explanation:

Force = mass x acceleration

1200 x 3.5 = 4200

Answer:

h = 1.8 m

Explanation:

The initial velocity of the glove, u =- 6 m/s

We need to find the maximum height of the glove. Let it is equal to h. Using equation of kinematics. At the maximum height v = 0

[tex]v^2-u^2=2ah[/tex], h is the maximum height and a = -g

[tex]0^2-(6)^2=2\times (-10)\times h\\\\h=\dfrac{36}{20}\\\\h=1.8\ m[/tex]

Hence, it will go up to a height of 1.8 m.

Answer:

A. Ovary

Explanation:

Answer:

Vf = 25.7 [m/s]

Explanation:

To solve this problem we must use the following kinematics equation:

[tex]v_{f} ^{2}= v_{i} ^{2}-(2*a*x)[/tex]

where:

Vf = final velocity [m/s]

Vi = initial velocity = 30 [m/s]

a = desacceleration = 2 [m/s^2]

x = distance = 60 [m]

Note: the negative sign in the equation means that the car slows down.

Now replacing:

[tex]v_{f}^{2}=(30)^{2}-(2*2*60)\\ v_{f}^{2} = 660\\v_{f} =\sqrt{660} \\v_{f}=25.7[m/s][/tex]

Answer:

[tex]the \: net \: force = \: 50 - 15 = 35.[/tex]

Answer:

Net force is going to be GREATER FORCE - LESS FORCE if they are working in opposite direction

so,

         50N - 15N = 35N

Answer:

W = 1590 J

Explanation:

We could use the formula of potential energy to find work as both have the same units,

                    W = mgh

since weight = mg so,

                     Work = weight x height

                               = 530 x 3

                               = 1590 J

Answer:

The work will be 1590 J

since the formula is W = F x D so I cancel the time

Explanation:

Given:

(Force) F = 530N

(Distance)D = 3m

Unknown:

W or Work

Formula and Solution:

W = F x D

W = (530N) (3m)

Final Answer:

W = 1 590 N·m or simplify as 1590 J

Explanation:

Note: I'm assuming the data 77.3 is the mass of the crate.

Answer:

[tex]\mu_s =0.36[/tex]

Explanation:

The coefficient of static friction, called \mu_s is the ratio between the force needed to start moving an object above a rough surface (Fr), and the normal force the surface exerts on the object (N).

[tex]\displaystyle \mu_s =\frac{Fr}{N}[/tex]

The normal force is numerical equivalent to the weight of the body if no other external forces are acting.

[tex]N=m\cdot g[/tex]

The mass of the crate is m=77.3 Kg, thus its weight and normal force is:

[tex]N=77.3\ kg\cdot 9.8\ m/s^2[/tex]

[tex]N= 757.54\ Nw[/tex]

Now we calculate the coefficient:

[tex]\displaystyle \mu_s =\frac{275\cancel{N}}{757.54\cancel{N}}[/tex]

[tex]\boxed{\mu_s =0.36}[/tex]

Answer:

Energy is found only in moving objects : False

Energy is never created : True

Energy can move matter : True

Energy is the same as force : False

Energy is never destroyed : True

Explanation:

Plato

Energy can neither be created nor be destroyed. Energy is generated by both moving and stationary objects but in different forms. Energy can move matter. Hence, options 2, 3 and 5 are correct.

According to the law of conservation of energy, energy can neither be created nor be destroyed. However, it can be transformed from one state to the other. For example electrical energy can be converted to light energy.

Energy is generated in both stationary and moving object. The energy for a particle gained by its motion is called its kinetic energy. The energy stored on an object at rest is called potential energy.

Energy can move matter as well. The energy used to displace an object is called work done on the object. The unit of energy and work done  is joule. Therefore, options 2, 3 and 5 are correct.

Answer:

Explanation:

Increasing the amount of current that flows through a wire increases the strength of an electromagnet.

An electromagnet is a type of magnet that is created by running an electrical current through a coil of wire. Unlike permanent magnets, which have a fixed magnetic field that cannot be adjusted, the magnetic field of an electromagnet can be turned on and off or adjusted by controlling the amount of current flowing through the coil.

The strength of an electromagnet depends on several factors, including the number of coils in the wire, the amount of current flowing through the wire, and the type of core material used in the coil. Electromagnets are widely used in various applications, such as in electric motors, generators, relays, MRI machines, and particle accelerators.

One of the advantages of electromagnets is that their magnetic field can be easily controlled by adjusting the amount of current flowing through the wire. This makes them useful in applications where the magnetic field needs to be turned on and off, or where a variable magnetic field is required.

Another advantage of electromagnets is that they can be designed to be much stronger than permanent magnets. This is because the strength of an electromagnet is directly proportional to the amount of current flowing through the coil, which can be increased or decreased as needed.

Here in this question,

This happens because an electromagnet is created when an electric current flows through a wire, generating a magnetic field around the wire. The strength of the magnetic field depends on the amount of current flowing through the wire.

When more current flows through the wire, the magnetic field around the wire becomes stronger. This is because the magnetic field is directly proportional to the current flowing through the wire, as well as the number of loops of wire in the coil.

Therefore, increasing the current flowing through a wire in an electromagnet will increase the strength of the magnetic field, resulting in a stronger electromagnet.

Answer:

As the mass of the object decreaes, the potential energy also decreases.

Explanation:

Answer:

magnitude and direction e.g acceleration,displacement

Answer:

The three ways thermal energy is transferred are;

1) Conduction

2) Convection

3) Radiation

Explanation:

1) The conduction of the heat from the open flame to the marshmallow is through the direct contact of the flame with the marshmallow, such that the flame the region of the combustion reaction, that produces light and heat touches the marshmallow

2) The convection process is the transfer of heat from the rising heated combustion products, as well as the heated air that rises from the flame

3) The radiation heat transfer is the transfer of the heat from the fire to the marshmallows directly by the heat the moves in the form of electromagnetic waves at temperatures above 1000 K, without the need for a medium, such that the marshmallow can be heated by the heat coming from side of the flame.

Since the forces are going in opposite directions, you can subtract them. Which makes it 7N south minus 5N North. That is 2N pointing South. Because the force going south is greater, it is the direction the force will be going.
