Answer:

solar wind

Explanation:

the sun's atmosphere is made of hydrogen which itself made subatomic particle. These particle are constantly boiling off the sun and streaming outward at very speed. So, the sun's magnetic field and particles are called solar wind.

A particle (mass = 5.0 g, charge = 40 mC) moves in a region of space where the electric field is uniform and is given by Ex = –2
taurus [48]

Answer: 40m

Explanation: Distance is a function of speed/ velocity and time.

From the question the velocity along the z axis is given as 20 m/s at t = 0 secs We were ask to calculate the distance travelled when t = 2secs.

Recall that,

Velocity = distance travelled / time

Since we're calculating for distance we make it subject of formula;

Distance travelled = velocity * time

= 20m/s * 2s

= 40meter.

Suppose you observed the equation for a traveling wave to be y(x, t) = A cos(kx − ????t), where its amplitude of oscillations wa
OLga [1]

Answer:

<h2>15m/s</h2>

Explanation:

The equation for a traveling wave as expressed as y(x, t) = A cos(kx − \omegat) where An is the amplitude f oscillation, \omega is the angular velocity and x is the horizontal displacement and y is the vertical displacement.

From the formula; k =\frac{2\pi x}{\lambda} \ and \ \omega = 2 \pi f where;

\lambda \ is\ the \ wavelength \ and\ f \ is\ the\ frequency

Before we can get the transverse speed, we need to get the frequency and the wavelength.

frequency = 1/period

Given period = 2/15 s

Frequency = \frac{1}{(2/15)}

frequency = 1 * 15/2

frequency f = 15/2 Hertz

Given wavelength \lambda = 2m

Transverse speed v = f \lambda

v = 15/2 * 2\\\\v = 30/2\\\\v = 15m/s

Hence, the transverse speed at that point is  15m/s

Mean arterial pressure is ________ (indirectly/directly) proportional to ________ and ________ (indirectly/directly) proportiona
g100num [7]

Answer: Mean Arterial Pressure is directly proportional to Cardiac Output and Systemic Vascular Resistance and also directly proportional to Central Venous Pressure.

Explanation: Based on the relationship of flow, pressure and resistance, the mean arterial pressure is determined by the cardiac output (CO), systemic vascular resistance (SVR), and central venous pressure (CVP). This relationship is given by:

MAP = (CO x SVR) + CVP

Which is alternatively expressed as:

MAP = CO x SVR (this is because at any point in time in blood circulation, the central venous pressure is always near to zero mmHg.

Due to this direct relationship, any factor affecting the cardiac output and the Systemic Vascular Resistance would cause a corresponding change in the Mean Arterial Pressure.

It is also worthy to note that If Cardiac Output and Systemic Vascular Resistance change reciprocally (inversely) and proportionately, then Mean Arterial Pressure will not change. The plotted graph is one of positive slope.

The whole relationship occurs when blood is pumped out of the left ventricle into the aorta and distributing arteries, creating pressure.

Your little sister (mass 25 kg) is sitting in her little red wagon (mass
Zielflug [23.3K]

Answer:

p = 60.6N*s

Explanation:

v_f = v_0+a*t

a = (v_f-v_0)/t

a = (1.8m/s)/2.35s

a = 0.77m/s²

F = m*a

F = (25kg+8.5kg)*0.77m/s²

F = 25.8N

^p = F*t

p = 25.8N*2.35s

p = 60.6N*s
