Answer: 0.25m/s2

Explanation:

Acceleration is change in velocity with time

V = final velocity = 5m/s

U =Initial velocity = 3m/s

t = time = 8s

a = Acceleration =?

a = V — U / t

a = (5 — 3) / 8

a = 2/8

a = 0.25m/s2

Acceleration formula is Vf-Vi divided by time. Final velocity = 5, Initial Velocity = 3, and time is 8.
So, do in a calculator (5-3) divided by 8.
Or step by step:
5-3 = 2
2/8 = 0.25
And units for acceleration is m/s/s (m/s squared) so it is 0.25m/s^2 (squared)

OLga [1]

Complete question is;

Which statements accurately describe the evidence that scientists gather using fossils? Check all that apply.

A) The fossil record can be used to date rocks.

B) Living things with many cells have always lived on Earth.

C) Simple organisms are found only in young rocks.

D) Geologists study ancient remains of plants and animals.

E) Scientists can figure out what ancient living things ate.

F) Pollen and seeds help provide clues about ancient climates.

Answer:

A) The fossil record can be used to date rocks

E) Scientists can figure out what ancient living things ate.

F) Pollen and seeds help provide clues about ancient climates

Explanation:

In scientific research, fossils are sometimes referred to as animals and plant. Now, in studying records of fossils, it will be easy to know the length of existence of living things on the Earth. Also, we can be able to identify the manner in which different relationships exists between plants and animals by predicting their lifestyles, location of their habitation e.t.c which can be used to predict the old time climates.

Looking at the options given in relation to the explanation given, options A, E & F are correct

Which hypothesis led to the discovery of the proton?
Viefleur [7K]
When a neutral hydrogen atom loses an electron a positively charged particle should remain. A proton is a subatomic particle, symbol p+, with a positive charge of +1e elementary charge and mass slightly less than that of a neutron.
Ernest Rutherford discovered that the atom must have a concentrated positive center charge that contains most of the atom's mass. He suggested that the nucleus contained a particle with a positive charge the proton.

Nezavi [6.7K]
Celsius to fahrenheit:

ºF = ºC x 1.8 + 32

ºF = 60 x 1.8 + 32

ºF = 108 + 32

= 140 ºF

Celsius to kelvin:

K = ºC +273.15

K = 60 + 273.15

 = 333.15 K

hope this helps dude!
