Determine the greatest force P that can be applied to the frame if the largest force resultant acting at A can have a magnitude of 5kN.

(a) The difference in temperature between these two planets is 17.6 °C.

(b) The expression of the temperature difference in Celsius is 17.8 °C.

The result is obtained by the formula for temperature conversion.

x °F = [5/9 (x - 32)] °C

x K = (x - 273.15) °C

(a) The average daytime temperature on Earth and Jupiter are 72°F and 313 K. Find the difference in temperature in Celsius!

We convert the two temperatures to Celsius.

72 °F = [5/9 (72 - 32)] °C

72 °F = [5/9 (40)] °C

72 °F = 22.22 °C

313 K = (313 - 273.15) °C

313 K = 39.85 °C

The temperature difference on Earth and Jupiter is

39.85 °C - 22.22 °C = 17,63 ≈ 17.6 °C

(b) If the temperature difference between day and night in Los Angeles is winter is 32 °F, find the expression in °C!

The temperature range of Celsius is 100 degrees and the temperature range of Fahrenheit is 180. If Δx in Fahrenheit is 32, Δx in Celsius is

x/32 = 100/180

x = (32×100)/180

x = 320/18

x = 17.8 °C

Hence, the temperature difference between the two planets is 17.6 °C and the between day and night in Los Angeles is 17.8 °C.

The complete question is-

Now suppose Bx>0 , and another electron is projected in the same manner. Which of the following is the most accurate qualitative description of the electron's motion once it enters the region of nonzero magnetic field?

a). The electron decelerates before coming to a halt and turning around while always moving along a straight line.

b). The electron's motion will be unaffected. (It will continue moving in a straight line with the same constant velocity.)

c). The electron moves in a circle in the xy plane.

d). The electron moves along a helical path about an axis parallel to the field lines with constant radius and constant velocity in the x direction.

The initial velocity of the car is 17 meters per second. It is accelerated at 3m/s^/2.

Acceleration is the rate of change in both speed and direction of velocity over time. When anything moves faster or slower in a straight line, it is said to have been accelerated. Because the direction is always shifting, motion on a circle accelerates even while the speed is constant.

Given -

A car moving on a straight road at 5 m/s.

It is accelerated at 3 m/s^2.

The first equation of motion is,

v = u + at

It gives the velocity acquired by a body in time t.

Here,

initial velocity = u

acceleration = a

time = t

final velocity = v

Therefore, now putting up the values.

v = u + at

→ u = 5 m/s

→ a = 3 m/s²

→ t = 4 sec

⇒ v = 5 + 3 × 4

⇒ v = 5 + 12

⇒ v = 17 m/s.

Thus, the initial velocity of the car is 17 meters per second.

A mass-containing object's velocity or acceleration can be altered by a force (for example, moving from a condition of rest). Force can also be intuitively described as a push or a pull. All objects with mass or energy are attracted to one another through the fundamental physics interaction of gravity (from the Latin gravitas, "weight").

Explanation:

The force of gravity on a woman who weighs 926 N on the surface of the earth is 926 N. The weight of an object is a measure of the force exerted on the object due to gravity, and is equal to the mass of the object multiplied by the acceleration due to gravity. On the surface of the Earth, the acceleration due to gravity is approximately 9.8 m/s^2.

Answer:926N

Explanation:

Force=926N.

The units of force are in N (Newtons). The units of weight are in Kg (Kilograms)

Force = Mass * Acceleration

On the surface of the Earth, the acceleration would be gravity, 9.81m/s²

If calculating mass...

F=mg

926N=m(9.81m/s²)

Therefore, the minimum surface temperature for a star whose emission peaks at a wavelength less than 400 nm is around 7248 K.

the minimum surface temperature of a star whose peak emission is in the ultraviolet, with a wavelength less than 400 nm.

The ultraviolet region of the spectrum is between about 10nm and 400nm, so for a wavelength of 400nm, we can use Wien's law to find the temperature:

400 x 10^-9m = 2.898 x 10^-3m K / T

T = 2.898 x 10^-3m K / (400 x 10^-9m)

T = 7248K (approximately)

If one block is 310 feet, he will travel 1,315.21 feet if he goes directly to school.

The British imperial and American customary systems of measurement both use the foot as a unit of length (standard symbol: ft). One alternate symbol that is frequently used is the prime symbol, ′. Since the International Yard and Pound Agreement of 1959, one foot is precisely equal to 0.3048 metres. One foot equals 12 inches in both customary and imperial units, while one yard equals three feet.

The "foot" has historically been a component of numerous regional systems of units, including the Greek, Roman, Chinese, French, and English systems. It varied in length from nation to nation, city to city, and occasionally trade to trade. Its length was typically between 250 mm and 335 mm, and it was typically, but not always, divided into 12 inches.

Given that:

Total block in north = 3

Total block in west = 3

1 block = 310 feet

Then,

Total distance in north = 3 × 310 = 930 feet

Total distance in west = 3 × 310 = 930 feet

Distance travelled by Drew = √(Total distance in north² + Total distance in west²)

Distance travelled by Drew = √(930² + 930²)

Distance travelled by Drew = √(864,900 + 864,900)

Distance travelled by Drew = √1,729,800

Distance travelled by Drew = 1,315.21 feet

We are given that the object is 15.0 cm tall and 12.0 cm away from the mirror, which has a focal length of 4.8 cm. The image is 8.0 cm in front of the mirror. By substituting the given values into the mirror equation, we can solve for d_i: 1/4.8 = 1/12 + 1/d_i. d_i = 8cmNow we can use the magnification equation m = -d_i/d_o = -8/12 = -2/3. The negative sign indicates that the image is inverted. We can use the magnification equation to calculate the height of the image:

h_i = m * h_o = h_i = (-2/3) * 15.0= h_i ≈ -10 cm

So the approximate height of the image is -10 cm.A concave mirror has a reflective surface that is curved inward and away from the light source.

The ball will hit the ground 54.4 meters from the base of the cliff. This can be determined using the equation for the horizontal range of a projectile, which is x = vx*t. In this case, vx is 11.5 m/s, and t is the time it takes for the ball to reach the ground. This time can be determined using the equation for the vertical range of a projectile, which is y = vyo*t + 0.5*g*t^2. In this case, vyo is 0 m/s (since the ball is thrown horizontally), g is 9.81 m/s^2, and y is 45.2 m (the height of the cliff). Solving for t gives us 3.86 seconds. Plugging this value into the equation for the horizontal range gives us x = 54.4 m.
