Bumek [7]3 years ago

Answer: When a car is parked in hot sunlight, the temperature of the car’s seats <u>increases</u> and the thermal energy of the seats <u>increases. </u>

Explanation:

The radiation of the Sun heats the air trapped inside the car which eventually heats everything inside the car including the seats of the car. The temperature of the seat rises.

The thermal energy is related to the kinetic energy of the constituent particles of a body. When a body is heated up, its temperature increases which in turn increases the kinetic energy of the particles thereby increasing the thermal energy of the body.

Here, rise in temperature of the seats increases the thermal energy of the seats.

__________ are combating competitive pressures by providing better value with private-label merchandise; adding new value-added
Neko [114]

Answer:

convinience store

Explanation:

convenience store are more like retail store providing everyday goods.

since this kind of store is usually small, maybe not as big as a department store, there is a growing number of such stores creating competitive pressures as such many are providing better value with private-label merchandise (more like re-branding or personalizing the products in the store)

A 269-turn solenoid is 102 cm long and has a radius of 2.3 cm. It carries a current of 3.9 A. What is the magnetic field inside
RUDIKE [14]

Answer:

Magnitude of the magnetic field inside the solenoid near its centre is 1.293 x 10⁻³ T

Explanation:

Given;

number of turns of solenoid, N = 269 turn

length of the solenoid, L = 102 cm = 1.02 m

radius of the solenoid, r = 2.3 cm = 0.023 m

current in the solenoid, I = 3.9 A

Magnitude of the magnetic field inside the solenoid near its centre is calculated as;

B = \frac{\mu_o NI}{l} \\\\

Where;

μ₀ is permeability of free space = 4π x 10⁻⁷ m/A

B = \frac{4\pi*10^{-7} *269*3.9}{1.02} \\\\B = 1.293 *10^{-3} \ T

Therefore, magnitude of the magnetic field inside the solenoid near its centre is 1.293 x 10⁻³ T

nordsb [41]

Answer:

W=3456 N

Explanation:

Force 1 F_1=3456

Force 2 F_2=2333N

Acceleration at stage 2 a_2=0.39

Generally the weight of the Craft W is given as

W= upward force(thrust)

Therefore

W=3456 N
