If a 10Ω resistor is removed and replaced by a 20Ω resistor, at constant voltage, the current will decrease.

This law states that, the current flowing in a conductor is directly proportional to the voltage in the conductor.

V = IR

where;

I = V/R

At constant voltage, when the value of the resistance increases, the value of the current in the ciircuit wil decrease.

Thus, if a 10Ω resistor is removed and replaced by a 20Ω resistor, at constant voltage, the current will decrease.

Answer:

s = 11.46 m

Explanation:

Since, the reaction time is 0.75 s. Hence, the brakes shall be applied after this time. So, the car will start to slow down after covering a distance at the constant speed during this time. This distance can be given as follows:

s = vt

where,

s = distance covered by car before slowing down = ?

v = speed of car = (55 km/h)(1 h/3600 s)(1000 m/1 km) = 15.28 m/s

t = reaction time = 0.75 s

Therefore,

s = (15.28 m/s)(0.75 s)

s = 11.46 m

Answer:

735 J

Explanation:

From the question given above, the following data were obtained:

Weight (W) = 49 N

Height (h) = 15 m

Potential energy =?

Potential energy is simply defined as the product of weight of the object and height to which the object is raised. Mathematically, it is expressed as:

Potential energy = weight × height

With the above formula, we can obtain the potential energy of the coconut as follow:

Weight (W) = 49 N

Height (h) = 15 m

Potential energy =?

Potential energy = weight × height

Potential energy = 49 × 15

Potential energy = 735 J

Thus, the potential energy of the coconut is 735 J

Answer:

the answer is B but I'm not completely sure

The reason for this observation is  that the shed is not made of iron or steel.

The special magnetic property of iron is called ferromagnetism. As a result of this special magnetic property, iron can be attracted easily by a magnet. Steel is made from iron so it is also highly magnetic.

In the question, a magnet placed against the wall of a metal shed falls to the ground, where it attracts a nail. The reason for this is that the shed is not made of iron or steel.

Answer:

The proximate answer pertaining to your question entails 10 kg.

Justification:

The statement implies which of the following units preceded by the value of 10 will obtain substantial inertia.

Exploiting conversions, this can be evinced/demonstrated:

Choice "10 m" => .01 kg

10 J ==> 0.10

10 N ==> 1.02 kg

10 kg  ==>  10 kg

Thus, an object obtaining a cumulative mass of 10 kg obtains substantial inertia.

Ben.

Explanation:

m = Mass Bonnie and Ben lift = 50 kg

s = Displacement of mass by both the students = 0.6 m

Work done by both the student is

[tex]W=Fs\\\Rightarrow W=10\times 50\times 0.6\\\Rightarrow W=300\ \text{J}[/tex]

The amount of work done by both the students will be equal to 300 J.

[tex]t_1[/tex] = Time taken by Bonnie = 1 minute = 60 seconds

[tex]t_2[/tex] = Time taken by Ben = 10 seconds.

Power delivered by Bonnie

[tex]P=\dfrac{W}{t_1}\\\Rightarrow P=\dfrac{300}{60}\\\Rightarrow P=5\ \text{W}[/tex]

Power delivered by Ben

[tex]P=\dfrac{W}{t_2}\\\Rightarrow P=\dfrac{300}{10}\\\Rightarrow P=30\ \text{W}[/tex]

So, power delivered by Ben is more.

The hormonal, cardiovascular, central nervous and respiratory systems are all involved in this response.

The body is equipped to respond to emergency situations through the fight and flight hormones secreted by the adrenal gland. This chemical messengers send a message to the brain which now causes reactions such as increased pumping of blood by the heart and a faster breathing rate by the lungs.

Answer:

I = 1.944 A

Explanation:

Given the following data;

Charge, Q = 3.5C

Time, t = 1.8 secs

Charge of a substance is given by the formula;

[tex] Q = It[/tex]

Where;

Q is the amount of charge measured in Colombs.

I is the current measured in Amperes.

t is the time measured in seconds.

Making I the subject of formula, we have

[tex] I = \frac {Q}{t} [/tex]

[tex] I = \frac {3.5}{1.8} [/tex]

I = 1.944 A

Therefore, the current in the circuit is 1.944 Amperes.

Answer:

85.66m

Explanation:

Given the following data;

Horizontal velocity = 25.8m/s

Height = 54m

Initial velocity = 0

We would first of all, solve for the time taken using the formula for maximum height of a projectile.

H = ½gt²

Where;

We know that acceleration due to gravity is 9.8m/s²

Substituting into the equation

54 = ½*9.8t²

54 = 4.9t²

t² = 54/4.9

t² = 11.02

t = 3.32 secs

To find the distance;

Distance, x = velocity * time

x = vt

Substituting into the equation, we have;

x = 25.8*3.32

x = 85.66m

Explanation:

Answer:

Student A is correct.

Explanation:

An electromagnet can be defined as the magnet that is produced by the electric current passing through a wire surrounding a metal piece. In an  electric motor, magnets surrounds the the coil carrying currents. Because of the magnetic field, the current carrying coil experiences a force and it starts to rotate. Thus the electric motors uses the forces between the electromagnets to start running.

Therefore, student A is correct.
