When an electromagnet has an iron core inserted, what happens to the strength of the magnet?.

Answers

Answer:

The strength of the electromagnet increases.

Explanation:

1. A racing car moving with constant acceleration covers two successive kilometres in 30 seconds and 50 seconds respectively. find the acceleration of the car.

2. A ball is thrown vertically upwards with a velocity of 20 metre per second from the top of a multi-storey building the height of the point from where the ball is from 25 m from the ground.​

Answers

The acceleration of the car is calculated as 10 m/s.

What is acceleration?

The acceleration is the rate of change of velocity with time. Given that;

s = ut + 1/2 at^2

Assuming that the motion started from rest, u = 0 m/s

s = 1/2 at^2

2000 = 0.5 * a * (20)^2

a = 2000/ 0.5 *  (20)^2

a = 10 m/s^2

2) The time taken to reach the maximum height is gotten from;

v=u+at

0=20+(−10)t

t=2s

Then time taken to reach the maximum height;

s = ut + 1/2 at^2

s = 20(2)+0.5(−10)(2)^2

s = 20m

The maximum height is therefore 45 m thus;

45=0+0.5(10)(t)^2

t = 3s

Total time= 3+2= 5s

Initial velocity = u

acceleration = a

1000 = u(30) + 0.5a(30)²

1000 = 30u + 450a

velocity after covering 1 km = u + 30a

1000= (u+30a) (20) + 0.5a (20)²

1000= 20u + 800a

u = 35a

putting the value of u in above equation

so, a = 2/3

Two cars, with the same mass and traveling at the same speed, hit large trees head-on. One car has a rigid body that undergoes little or no deformation in the collision. The other has ``crumple zones'': portions of the body designed to crumple and deform in such a collision. How does this improve the chances that the driver of the second car will survive the event

Answers

The crumple zones in the second car will improve the chance of survival of the driver because it will act as shock absorber, reducing the impact of the force on the driver.

Newton's third law of motion

According to Newton's third law of motion, action and reaction are equal and opposite.

The car with rigid body will exert maximum force to the driver while the car with crumple zone will exert lesser force to the driver since the crumple zone will act as shock absorber, reducing the impact of the force on the driver.

Thus, the crumple zones in the second car will improve the chance of survival of the driver because it will act as shock absorber, reducing the impact of the force on the driver.

When your hand presses down on scissors, the force is called input force because are applying a force into an object. Thus, option a is correct.

What is force ?

Force is an external agent acting on a body to deform it or to change its state from rest or motion. There are various kinds of force such as magnetic force, nuclear force, gravitational force etc.

Force is a vector quantity thus, it is characterised by a magnitude and direction. According to second law of motion, the force acting on a body is the product of mass and acceleration.

Hence, the force acting on a body is directly proportional to the mass. Greater the mass, greater will be the force needed to accelerate the body. When we press down on an object we are applying an input force to the object.

A metal block has a density of 5000 kg per cubic meter and a mass of 15,000 kg. What is its volume?

Answers

Taking into account the definition of density, the volume of the metal block is 3 m³.

What is density

Density is defined as the property that matter, whether solid, liquid or gas, has to compress into a given space.

In other words, density is a quantity that allows us to measure the amount of mass in a certain volume of a substance.

Then, the expression for the calculation of density is the quotient between the mass of a body and the volume it occupies:

[tex]density=\frac{mass}{volume}[/tex]

From this expression it can be deduced that density is inversely proportional to volume: the smaller the volume occupied by a given mass, the higher the density.

Volume of the metal block

In this case, you know that:

Density= 5000 [tex]\frac{kg}{m^{3} }[/tex]Mass= 15000 kgVolume= ?

Replacing in the definition of density:

[tex]5000 \frac{kg}{m^{3} } =\frac{15000 kg}{volume}[/tex]

Solving:

volume×5000 [tex]\frac{kg}{m^{3} }[/tex]= 15000 kg

volume= [tex]\frac{15000 kg}{5000 \frac{kg}{m^{3} }}[/tex]

volume= 3 m³

Answers

The velocity of the 2x10^4 kg car just before the collision is 0 m/s.

What is conservation of momentum principle?

When two bodies of different masses move together each other and have head on collision, they travel to same or different direction after collision.

The external force is not acting here, so the initial momentum is equal to the final momentum. For inelastic collision, final velocity is the common velocity for both the bodies.

m₁u₁ +m₂u₂ =(m₁ +m₂) v

Substitute the values for m₁ = 1.5 x 10^4 kg, m₂ =2 x 10^4 kg and u₁ =7 m/s, the final velocity is 3m/s/

1.5 x 10^4 x 7+2 x 10^4 x u₂ = (1.5 x 10^4 + 2 x 10^4) x 3

u₂  = 0 m/s

Answers

Explanation:

Hello !

Archimedes' principle

''states that the upward buoyant force that is exerted on a body immersed in a fluid, whether fully or partially, is equal to the weight of the fluid that the body displaces.''

Archimedes principle equation is given as

buoyant force = density of fluid x volume of displaced fluid x acceleration due to gravity. or

Fb=-density*gravity*volume

For example, a ship that is launched sinks into the ocean until the weight of the water it displaces is just equal to its own weight.

Answer:

Archimedes principle states that"When a body is totally or partially immersed in a liquid,it experience an upthrust which is equal to the weight of the liquid displaced"

This shows that the weight of liquid displaced when a certain object is placed in water is equal to the weight of the object.

Answers

The total cost for the energy used if electricity costs 10p per unit is determined as 2p.

Total energy consumed

The total energy consumed during the process is calculated as follows;

E = Pt

where;

P is power (kW)t is time (hr)

E = (800 W/1000) x (2.5 /60)   + (2 kW) x (5/60)

E = 0.8 kW x 0.042 hr     +    2kW x 0.083 hr

E = 0.0336 kW-hr  +  0.166 kW-hr

E = 0.1996 kW-hr

Cost of the energy consumption

C = E x 10p

C = 0.1996 kW-hr x 10p

C = 1.996p

The equivalent resistance of the circuit will be option (D) 80.0 Ω

The obstruction to current flow in an electrical circuit is measured by resistance. The Greek letter omega (Ω) represents the unit of measurement for resistance, known as ohms. Georg Simon Ohm is the name given to ohms.

Since in the given figure the resistance are in series so there equivalent resistance will be sum of the two resistance. If they were in parellal connection then we will add reciprocal of their resistance.

Let R1 = 60 Ω and R2 = 20 Ω. So their equivalent resistance will be as follow:

R = R1 + R2

R = 60 + 20

R = 80 Ω

A force of 5N produces an acceleration of 8m/s2 on mass m1, and an acceleration of 24m/s2 on a mass m2. What acceleration would the same force provide if both the masses are tied together.

Answers

The acceleration that the same force will provide if both masses are tied together is; 6.0 m/s².

How to find the Acceleration?

We are given;

Force; F = 5 N

Acceleration of the first mass, a₁ = 8.0 m/s²

Acceleration of the second mass, a₂ = 24 m/s²

Formula for force is;

F = ma

Let us find both masses; m₁ and m₂.

m₁ = F/a₁

m₂ = F/a₂

Thus;

m₁ = 5/8 kg

m₂ = 5/24 kg

Total mass is; m = m₁ + m₂

m = 5/8 + 5/24

m = 15 + 5/24

m = 20/24 kg
