Answer:

65°

Explanation:

In any triangle, the sum of the three internal angles makes 180°.

In this problem, we have a right triangle, which means that one angle is 90°. We are also told that another angle is 25°, so if we call x the unknown angle, we must have:

90° + 25° + x = 180°

Re-arranging the equation, we can solve to find the value of x:

x = 180° - 90° - 25° = 65°

75 because 25 plus 75 equals 90

umka2103 [35]

Answer:

Planetary are deflected to right due to Coriolis effect.

Explanation:

The term Coriolis effect is defined as an effect in which the rotating object experience a force called as coriolis force which acts perpendicular to the axis of rotation and direction of motion. The effect talks about how the moving objects like ocean currents, wind are deflected due to the rotation of earth.

Winds and ocean currents are strongly affect by this effect.

In the year 2000, a company made $4.7 million in profit. For each consecutive year after that, their profit increased by 15%. Ho

olya-2409 [2.1K]

Answer: $8.2 million.

Explanation:

If we have a quantity A, and we have an increase of x%, this can be written as:

A + (x%/100%)*A

Now, for this particular case we have:

In year 2000 (we can define this year as the year zero, y = 0) the initial value is $4.7 million.

The next year, y = 1, there is an increase of 15%, then we will have a profit of:

P = $4.7 million + (15%/100%)*$4.7 million = $4.7 million + 0.15*$4.7 million

P = $4.7 million*(1 + 0.15) = $4.7 million*(1.15)

in the next year, y = 2, the profit will be:

P = $4.7 million*(1.15) + (15%/100%)* $4.7 million*(1.15)

= $4.7 million*(1.15) + 0.15* $4.7 million*(1.15)

= $4.7 million*(1.15)^2

We already can see the pattern, the profit in the year y will be:

P(y) = $4.7 million*(1.15)^y

In particular, in the year 2004 we have y = 4, then the profit that year will be:

P(4) = $4.7 million*(1.15)^4 = $8.2 million.

A block of mass 0.510 kg is pushed against a horizontal spring of negligible mass until the spring is compressed a distance x. T

maria [59]

Answer:

x=0.46m, speed=7.9m/s

Explanation:

Using the concept of conservation of energy:

1. kinetic energy of mass m and velocity v: $E_k=\frac{1}{2}mv^2$

2. gravitational potential energy of mass m, grav. acc. g and height h: $E_g=mgh$

3. potential energy in a spring with spring constant k and displacement from equilibrium x: $E_s=\frac{1}{2}kx^2$

Calculating x:

$\frac{1}{2}mv_a^2=\frac{1}{2}kx^2$

$x=\sqrt{\frac{m}{k}}v_a$

Calculating the speed:

$\frac{1}{2}mv_a^2 +mgh_a=\frac{1}{2}mv_b^2+mgh_b + W_{friction}$

$h_a=0, h_b=2R,W_{friction}=F_{friction}\times distance=7\pi R$

$\frac{1}{2}mv_a^2=\frac{1}{2}mv_b^2+2mgR+7\pi R$

Solving for $v_b$ :

$v_b=\sqrt{v_a^2-4gR-14\pi\frac{R}{m}}$

Why is water not suitable for a biometric fluid?

stiv31 [10]

Answer: water cannot be used as barometric liquid because it's density is lower than Mercury . water's density is 1000 gram per cubic meter. hence it requires a barometer whose height is around 11 meters.
