Answer:

temperature for which two scales are same is given as

x = - 40^oC

Explanation:

As we know that temperature scales are linear function

so we can compare two temperature scales by

\frac{T_c - T_f}{T_b - T_f} = constant

now we have

\frac{T_c - 0}{100 - 0} = \frac{T_f - 32}{212 - 32}

here we know that

T_c = T_f = x

so we have

\frac{x - 0}{100} = \frac{x - 32}{180}

1.8 x = x - 32

x = - 40^oC

A block is on a ship. Its weight is 45 N. The gravity acceleration g = 10 N/kg. When the block is brought to a space station sur
DiKsa [7]

Answer:

4.5 kg

Explanation:

Since weight, W = mg where m = mass and g = gravity acceleration = 10 N/kg and W = 45 N

m = W/g

= 45 N/10 N/kg

= 4.5 kg

The mass of the block on the ship is thus 4.5 kg. Since mass is an intrinsic property of a substance and does not change with location, the mass of the block when it is brought to as space station surrounding the earth is also 4.5 kg.

The weight of an astronaut plus his space suit on the moon is only 291 n. how much (in n) do they weigh on earth? (the accelerat
Oksanka [162]
Weight on the Moon = 291 N.
W = g · m, where m stays for the mass and on the Moon g = 1.67 m/s²
291 N = 1.67 m/s² · m
m = 291 kg m / s² : 1.67 m/s²
m = 174.25 kg
Weight on Earth = 9.81 m/s² · 174.25 kg = 1,709.4 N
Answer:
The weight of an astronaut on Earth is 1,709.4 N.

Describe three pieces of evidence that support the Big Bang theory
lisov135 [29]

Explanation :

According to astronomers, the whole universe is started with a giant explosion called as Big Bang. Big Bang theory shows that the universe is  extended from high density state.

There are some evidence for big bang as :

(1) There are some red shifts of different galaxies which means that the universe is expanding.  

(2) Due to the expanding of universe, some of the new elements are created like hydrogen, deuterium etc.

(3) Microwaves are detected by orbiting detectors.

All this parameters shows that big bang theory was correct.
