Answer: sensoriomotor stage.

Explanation:

The characteristics fescribed correspond to Piaget's sensoriomotor stage. The sensorimotor stage covers children from birth to 18–24 months old. Some characteristics are motor activity without use of symbols, learning through experience, repetition and trial and error. The objective of this stage is to understand object permanence and distinvtion of self and others.

How many electrons does it take to make up 4.33 C of charge?
Dovator [93]

Answer:

Number of electrons, n=2.7\times 10^{19}

Explanation:

It is given that,

Charge, q = 4.33 C

We need to find the number of electrons that make 4.33 C of charge. According to quantization of charge as :

q=ne

n = number of electrons

e = electron's charge

n=\dfrac{q}{e}

n=\dfrac{4.33\ C}{1.6\times 10^{-19}\ C}

n=2.7\times 10^{19}

So, the number of electrons are 2.7\times 10^{19} Hence, this is the required solution.

If this speed is based on what would be safe in wet weather, estimate the radius of curvature for a curve marked 50 km/h . The c
PtichkaEL [24]

Answer:

Explanation:

v = 50 km / h

= 13.89 m /s

When a vehicle runs on a circular path , it is static friction which prevents it from getting overturned .

static friction = μs mg

centripetal force = m v² / R

m v² / R = μs mg

R = v² / μs x g

= 13.89² / .7 x 9.8

= 28.12 m .

3. Will the weight of a kg of iron in air and the weight of a kg of cotton in air
larisa [96]

Answer:

A kg of cotton is heavier.

Explanation:

Because in air, cotton gets upthrust that's why weighing machine gives less weight than its actually have.

for eg: If cotton has 800g weight, the machine shows a kg(1kg) when measure in air due to upthrust.

I hope this will be helpful for you.

A 5.00 g bullet traveling 355 m/s is stopped by lodging in the side of a building. The heat produced is shared between the build
steposvetlana [31]

Answer:

Explanation:

Given

mass of bullet m=5\ gm

speed of bullet v=355\ m/s

bullet is stopped by building and heat produced is shared between building and bullet

Kinetic Energy of bullet is converted into Thermal energy

Kinetic Energy of bullet K=\frac{1}{2}mv^2

K=0.5\times 5\times 10^{-3}\times (355)^2

K=315.06\ J

So 315.06 J of Energy is converted in to thermal energy
