Why do the metal stensils have wood handles?​

Physics
1 answer:
pickupchik [31]3 years ago
4 0

Answer:

Handles of cooking utensils are made of wood because wood is insulator of heat and so does not get heated while cooking. If they will be made of iron then it will get heated and we will not be able to hold them. Plastic is used to make handles of cooking utensils because it is also insulator of heat.

A spaceship orbiting earth flies to the moon. How is the gravitational force pulling on the spaceship related to the distance th
ad-work [718]
The correct answer is "<span>As the distance from the earth increases, the gravitational pull on the spaceship would decrease."

In fact, the gravitational force (attractive) exerted by the Earth on the spaceship is given by
</span>F=G \frac{Mm}{d^2}
where G is the gravitational constant, M the Earth's mass, m the mass of the spaceship and d the distance of the spaceship from the Earth. As we can see from the formula, as the distance d between the spaceship and the Earth increases, the gravitational force F decreases, so answer D) is the correct one.

Two long, parallel wires are separated by 2.0 m. Each wire has a 28-A current, but the currents are in opposite directions. Part
BlackZzzverrR [31]

Given Information:  

Current = I = 28 A

distance between wires = r = 2.0 m

Required Information:  

Magnetic field = B = ?

Answer:  

B = 12x10⁻⁶ T

Step-by-step explanation:  

Biot-Savart Law is given by  

B = μ₀I/2πr

Where μ₀ is the permeability of free space, I is the current flowing through the wire and B is the magnitude of the magnetic field produced.  

We are asked to find the magnetic field midway between the wires so r/2 = 1

B = 4πx10⁻⁷*28/2π*1

B = 6x10⁻⁶ T

since the same amount of current flows in both wires therefore, equal amount of magnetic field will be produced in both wires

B = 2*6x10⁻⁶ T

B = 12x10⁻⁶ T

Therefore, the net magnetic field midway between the two wires is 12x10⁻⁶ T.

A 440 kg roller coaster car is going 26 m/s when it reaches the lowest point on the track. If the car started from rest at the t
yawa3891 [41]
The only thing acting as the roller coaster gets to the bottom is gravity thus
acceleration is 9.81

so u use the formula
vf^2 = vi^2 + 2abetaD
thus
distance = vf^2 - vi^2 divided by 2a
so 26^2 - 0^2 divided by 2(9.81m/s)
equals 676 divided by 2(9.81m/s)
= 34.45463812m
then use the appropriate 3 sig digs
so 34.5m
hopes this helps

If the cost estimate for a project is a basis for contract awards and performance reporting, it should be a(n) _____ estimate an
Ratling [72]

Answer:

Definitive

Explanation:

Definitive estimate should be done very early in a project or even before a project is officially started and is used for making many purchasing decisions for which accurate estimates are required and for estimating final project costs. Therefore, if the cost estimate for a project is a basis for contract awards and performance reporting, it should be definitive estimate and as accurate as possible.
