The answer is 84N, but what is the mass and weight calculation?

Monica [59]

Answer:

weight= density ×volume× 9.8

mass=density×volume

Explanation:

$weight = 0.12 \times 0.04 \times 0.04 \times 3.14 \times 13600 \\ \times 9.8 = 80.351 \: n \\ \\ mass = 0.12 \times 0.04 \times 0.4 \times 3.14 \times 13600 = \\ = 8.199 \: kg$

f a car is speeding down a road at 40 miles/hour (mph), how long is the stopping distance D40 compared to the stopping distance

Oksana_A [137]

Answer:

D40 = 2.56 × D25

so number is 2.56 multiple of stopping distance @ 25 mph

Explanation:

given data

speed = 40 miles / hour

distance = D40

speed limit = 25 miles / hour

distance = D25

to find out

express number a multiple of stopping distance @ 25 mph

solution

we know here stopping distance is directly proportional to (speed)²

so here speed ratio is

initial speed = $\frac{40}{25}$

so initial speed = 1.6

stopping distance increase = (1.6)²

$\frac{D40}{D25}$ = (1.6)²

$\frac{D40}{D25}$ = 2.56

so here

D40 = 2.56 × D25

so number is 2.56 multiple of stopping distance @ 25 mph

Answer:

Option C

Explanation:

Metal conducts heat much better than wood does.

Since Azam's hand is hotter than room temperature, both the metal and the wood conduct heat away from it.

Calculate the maximum absolute uncertainty for R if:

erma4kov [3.2K]

Answer:

ΔR = 5 s

Explanation:

The absolute uncertainty or error in an expression is

ΔR = | $\frac{dR}{dB}$ | ΔB + | $\frac{dR}{dA}$ | ΔA

the absolute value guarantees to take the unfavorable case, that is, the maximum error.

We look for the derivatives

$\frac{dR}{dB}$ = 1

$\frac{dR}{dA}$ = -1

we substitute

ΔR = 1 ΔB + 1 ΔA

of the data

ΔB = 3 s

ΔA = 2 s

ΔR = 3 + 2

ΔR = 5 s

Is everyone in your class able to hear a quiet sound equally well?

Sergio039 [100]

Answer:

Explanation:

Loudness describes how people perceive sound (see loudness). ... If people could hear equally well at all frequencies, the contour lines would be flat because the same measured sound intensity would be perceived to be equally loud regardless of the sound frequency. In fact, people do not hear as well at low frequencies.
