0.0000004. since it is 10^-7 (note the negative), you would move thedecimal point 7 places to the left.

Answer:

C/100 = (F-32) / 180

or, C/5 = (F-32)/9

Explanation:

relation between any two scales is given by:

(X- lower fixed point ) / (upper fixed point -lower fixed point)

where X is any temperature

The planet Saturn has a mass that is 95 times Earth's mass and a radius that is 9.4 times Earth's radius. What is the accelerati

ziro4ka [17]

Answer:

10.55111 m/s²

Explanation:

M = Mass of Saturn = $95\times 5.972\times 10^{24}\ kg$

r = Radius of Saturn = $9.4\times 6.371\times 10^6\ m$

G = Gravitational constant = 6.67 × 10⁻¹¹ m³/kgs²

Acceleration due to gravity is given by

$g=\dfrac{GM}{r^2}\\\Rightarrow g=\dfrac{6.67\times 10^{-11}\times 95\times 5.972\times 10^{24}}{(9.4\times 6.371\times 10^6)^2}\\\Rightarrow g=10.55111\ m/s^2$

The acceleration due to gravity on Saturn is 10.55111 m/s²

Batman (mass = 88.8 kg) jumps straight down from a bridge into a boat (mass = 530 kg) in which a criminal is fleeing. The veloci

hram777 [196]

Answer:

The velocity of the boat after Batman lands in it is 2.08 m/s.

Explanation:

Given that,

Mass of batman $m_{1}= 88.8\ kg$

Mass of boat $m_{2}=530\ kg$

Initial velocity = 14.5 m/s

We need to calculate the velocity of boat

Using conservation of momentum

$m_{1}u=(m_{1}+m_{2})v$ ...(I)

Where, $m_{1}$ =mass of batman

$m_{2}$ =mass of boat

u=initial velocity

v = velocity of boat

Put the value in the equation

$88.8\times14.5=530+88.8\times v$

$v=\dfrac{88.8\times14.5}{530+88.8}$

$v=2.08\ m/s$

Hence, The velocity of the boat after Batman lands in it is 2.08 m/s.
