Answer:

Density of object, d = 4.76 g/cm³

Explanation:

It is given that,

Mass of the object, m = 50 g

Volume of the object, V = 10.5 cm³

We need to find the density of the object. The mass per unit volume of the object is called its density. It is given by :

d=\dfrac{m}{V}

d=\dfrac{50\ g}{10.5\ cm^3}

d = 4.76 g/cm³

So, the density of the object is 4.76 g/cm³. Hence, this is the required solution.

The density is 4.76 gcm^-3
and if mass is in kg then density is equal to 4.76*10^-3

Zepler [3.9K]
S(travel distance)=85 ft
v (velocity)=15 ft/s
-----------------------------------
t (time)=?

Calculate the time with the formula for the velocity:
v=S/t
t=S/v
t=85 ft/(15 ft/s)
t=5.666s

A wire of Nichrome (a nickel-chromium-iron alloy commonly used in heating elements) is 1.3 m long and 1.6 mm2 in cross-sectional
fredd [130]

Answer: 1.3 *10^6 Ω*m

Explanation: In order to explain this problem we have to use the following expression for the resistence:

R=L/(σ*A) where L and A are the length and teh area for the wire, respectively. σ is the conductivity of teh Nichrome.

Then, from mteh OHM law we have V=R*I so R=V/I=2/3.2=0.625 Ω

Finally we have:

σ=L/(R*A)=1.3/(0.625*1.6*10^-6)=1.3*10^6 Ω*m

Paha777 [63]

Answer:

u = - 38.85 m/s^-1

Explanation:

given data:

acceleration = 2.10*10^4 m/s^2

time = 1.85*10^{-3} s

final velocity = 0 m/s

from equation of motion we have following relation

v = u +at

0 =  u + 2.10*10^4 *1.85*10^{-3}

0 = u + (21 *1.85)

0 = u + 38.85

u = - 38.85 m/s^-1

negative sign indicate that the ball bounce in opposite directon
