Answer:

Correct answers:

Explanation:

• It is a satellite that collects data about rain and snow.

GPM is part of NASA's Earth Systematic Missions program and its function is to track precipitation from space with satellites and to provide accurate information of the time, place an amount of rain or snow anywhere in the world.

• Its orbit covers 90 percent of Earth's surface.

GPM has unique perspective on measuring precipitation from space because of their collected satellite retrievals.

• The sensors measure microwaves.

GPM Microwave Imager (GMI) is a sensor that observes the microwave energy emitted by the Earth and atmosphere, so it improves the accuracy of rain and snowfall estimates.

In a car collision, is it better for the passenger if the change in momentum is over a short period of time or a long period of

e-lub [12.9K]

Explanation:

The force on the passenger will be F = ma

Here, m does not change, but a is the variable.

If the cars slows down very fast, the acceleration will be higher, and thus the force will be higher.

If the acceleration is lower, the force will be lower as well, which would be the most desirable scenario for the passenger.

How much heat is needed to raise the temperature of 100 g of water by 50 C, if the specific heat of water is 4,184 J/kg.C?

Yuliya22 [10]

Heat required to raise the temperature of water is given as

$Q = ms\Delta T$

here we have

m = 100 g = 0.100 kg

s = 4183 J/kg C

$\Delta T = 50 ^0 C$

now we can use the above equation

$Q = 0.100 * 4184 * 50$

$Q = 20920 J$

so here it requires 20920 J heat to raise the temperature of 100 g water by 50 degree C

In April 1974, Steve Prefontaine completed a 10 km race in a time of 27 min, 43.6 s. Suppose "Pre" was at the 8.13 km mark at a

SOVA2 [1]

Answer: $0.084 m/s^2$

Explanation:

Given

Total time=27 min 43.6 s=1663.6 s

total distance=10 km

Initial distance $d_1=8.13 km$

time taken=25 min =1500 s

initial speed $v_1=\frac{8.13\times 1000}{25\times 60}=5.6 m/s$

after 8.13 km mark steve started to accelerate

speed after 60 s

$v_2=v_1+at$

$v_2=5.6+a\times 60$

distance traveled in 60 sec

$d_2=v_1\times 60+\frac{a60^2}{2}$

$d_2=336+1800 a$

time taken in last part of journey

$t_3=1663.6-1560=103.6 s$

distance traveled in this time

$d_3=v_2\times t_3$

$d_3=\left ( 5.6+a\times 60\right )103.6$

and total distance $=d_1+d_2+d_3$

$10000=8.13\times 1000+336+1800 a+\left ( 5.6+a\times 60\right )103.6$

$1870=336+1800 a+\left ( 5.6+a\times 60\right )103.6$

$a=0.084 m/s^2$

Suppose you have a device that extracts energy from ocean breakers in direct proportion to their intensity. If the device produc

babymother [125]

Answer:

2.81 kW

Explanation:

Initial power output, P = 20.0 kW

Initial amplitude, A = 1.20 m

Final Amplitude, A = 0.450 m

Power is proportional to extracted energy which is proportional to the intensity of the wave and intensity of the wave is directly proportional to the square of the amplitude.

P ∝ E ∝ I ∝ A²

$\frac{P'}{P}=\frac{A'^2}{A^2}$

Substitute the values to find the value of power produced:

$P'=\frac{0.450^2}{1.20^2}\times 20.0 kW=2.81 kW$
