Answer:

Due to the shortcomings in Piaget’s approach to cognitive development several other theories were put forward.

Explanation:

Jean Piaget is the psychologist that offered explanations about cognitive development in children. There were several shortcomings in his theories and thus alternative theories about cognitive development in children were developed.

Lev Vygotsky proposed another explanation to children’s cognitive development. He strongly emphasized on the influence of culture on children’s cognitive development. He believes that it is through socio-cultural interactions development progresses.

He believed that individualized thoughts begin after these interactions. He take on self-speech  was different from Piaget. Vygotsky considered self-speech as a guide to thinking while Piaget thought self-speech to be egocentric.

Answer:

1. chemical energy --> electrical energy --> light energy

2. Electrical Energy --> Mechanical Energy

3. Electrical Energy --> Heat Energy

4. Chemical Energy --> Thermal Energy --> Mechanical Energy

5. Nuclear Energy --> Light energy and thermal energy

6. Mechanical Energy --> Electric Energy

7. Chemical Energy --> Electrical Energy --> Sound Energy

8. Mechanical Energy --> Sound Energy

Explanation:

1.FLASHLIGHT:

chemical energy --> electrical energy --> light energy

The chemical energy from the cell batteries is converted to electrical energy, which is used to produce the light energy in form of flashlight.

2.ELECTRIC SAW:

Electrical Energy --> Mechanical Energy

The electrical energy from the socket is converted to the mechanical energy used to run the saw blade.

3.TOASTER:

Electrical Energy --> Heat Energy

The electrical energy from the socket is converted to the heat energy (thermal energy) used in browning the bread.

4.GAS POWERED SCOOTER:

Chemical Energy --> Thermal Energy --> Mechanical Energy

The chemical energy from fuel, such as petrol is converted to heat (thermal energy) in the engine by the process of combustion. This heat is then used to do work by conversion into mechanical energy, through piston movement, which in turn moves the shaft and the scooter.

5.THE SUN:

Nuclear Energy --> Light energy and thermal energy

The nuclear reactions on Sun provide nuclear energy which is converted into light and thermal energy that reaches us on earth.

6.WIND TURBINE:

Mechanical Energy --> Electric Energy

The mechanical energy is provided by wind when it rotates the blade of turbine. This is then converted to electrical energy b the turbine.

7.IPOD:

Chemical Energy --> Electrical Energy --> Sound Energy

The chemical energy i supplied by the battery of ipod, which is converted to electrical energy and that electrical energy is used to produce sound by ipod.

8.SPEAKER VIBRATES

Mechanical Energy --> Sound Energy

The mechanical energy due to vibration produces sound energy.

A 1423-kg car is moving along a level highway with a speed of 26.4 m/s. The driver takes the foot off the accelerator and the ca

Leona [35]

Answer:

Final speed, v = 28.81 m/s

Explanation:

Given that,

Mass of the car, m = 1423 kg

Initial speed of the car, u = 26.4 m/s

Force experience by the car, F = 901 N

Distance, d = 106 m

To find,

The speed of the car after traveling this distance.

Solution,

The force experienced by a car is equal to the product of mass and acceleration.

$F=ma$

$a=\dfrac{F}{m}$

$a=\dfrac{901}{1423}$

$a=0.63\ m/s^2$

Let v is the final speed of the car. Using third equation of motion to find it as :

$v^2-u^2=2ad$

$v^2=2ad+u^2$

$v^2=2\times 0.63\times 106+(26.4)^2$

v = 28.81 m/s

So, the final speed of the car is 28.81 m/s.

Find the magnitude and direction for 101m,60.0,85.0m

Crank

Answer:

magnitude = 161.3m, ∅ = 32.9°

Explanation:

Vector addition always works the same. Add two vectors by adding their respective components.

vector A: $\left[\begin{array}{c}85.0&0.0\end{array}\right]$

vector B: $101.0\left[\begin{array}{c} cos60.0&sin 60.0\end{array}\right] =\left[\begin{array}{c}50.5&87.5\end{array}\right]$

Adding vector A and B: $\left[\begin{array}{c}85.0&0.0\end{array}\right] +\left[\begin{array}{c}50.5&87.5\end{array}\right] = \left[\begin{array}{c}135.5&87.5\end{array}\right]$
